  • Prevent "jQuery( html )" from triggering the browser to request images and other referenced content

    - by Chris Dutrow
    Using jQuery to create new DOM elements from text. Example: jQuery('<div><img src="/some_image.gif"></img></div>'); When this statement is executed, it causes the browser to request the file 'some_img.gif' from the server. Is there a way to execute this statement so that the resulting jQuery object can be used from DOM traversal, but not actually cause the browser to hit the server with requests for images and other referenced content? Example: var jquery_elememnts = jQuery('<div><img class="a_class" src="/some_image.gif"></img></div>'); var img_class = jquery_elememnts.find('img').attr('class'); The only idea I have now is to use regex to remove all of the 'src' tags from image elements and other things that will trigger the browser requests before using jQuery to evaluate the HTML. How can jQuery be used to evaluate HTML without triggering the browser to make requests to the server for referenced content inside the evaluated HTML? Thanks!

  • JMX Based Monitoring - Part Three - Web App Server Monitoring

    - by Anthony Shorten
    In the last blog entry I showed a technique for integrating a JMX console with Oracle WebLogic which is a standard feature of Oracle WebLogic 11g. Customers on other Web Application servers and other versions of Oracle WebLogic can refer to the documentation provided with the server to do a similar thing. In this blog entry I am going to discuss a new feature that is only present in Oracle Utilities Application Framework 4 and above that allows JMX to be used for management and monitoring the Oracle Utilities Web Applications. In this case JMX can be used to perform monitoring as well as provide the management of the cache. In Oracle Utilities Application Framework you can enable Web Application Server JMX monitoring that is unique to the framework by specifying a JMX port number in RMI Port number for JMX Web setting and initial credentials in the JMX Enablement System User ID and JMX Enablement System Password configuration options. These options are available using the configureEnv[.sh] -a utility. Once this is information is supplied a number of configuration files are built (by the initialSetup[.sh] utility) to configure the facility: spl.properties - contains the JMX URL, the security configuration and the mbeans that are enabled. For example, on my demonstration machine: spl.runtime.management.rmi.port=6740 spl.runtime.management.connector.url.default=service:jmx:rmi:///jndi/rmi://localhost:6740/oracle/ouaf/webAppConnector jmx.remote.x.password.file=scripts/ouaf.jmx.password.file jmx.remote.x.access.file=scripts/ouaf.jmx.access.file ouaf.jmx.com.splwg.base.support.management.mbean.JVMInfo=enabled ouaf.jmx.com.splwg.base.web.mbeans.FlushBean=enabled ouaf.jmx.* files - contain the userid and password. The default setup uses the JMX default security configuration. You can use additional security features by altering the spl.properties file manually or using a custom template. For more security options see the JMX Site. Once it has been configured and the changes reflected in the product using the initialSetup[.sh] utility the JMX facility can be used. For illustrative purposes, I will use jconsole but any JSR160 complaint browser or client can be used (with the appropriate configuration). Once you start jconsole (ensure that splenviron[.sh] is executed prior to execution to set the environment variables or for remote connection, ensure java is in your path and jconsole.jar in your classpath) you specify the URL in the spl.management.connnector.url.default entry and the credentials you specified in the jmx.remote.x.* files. Remember these are encrypted by default so if you try and view the file you may be able to decipher it visually. For example: There are three Mbeans available to you: flushBean - This is a JMX replacement for the jsp versions of the flush utilities provided in previous releases of the Oracle Utilities Application Framework. You can manage the cache using the provided operations from JMX. The jsp versions of the flush utilities are still provided, for backward compatibility, but now are authorization controlled. JVMInfo - This is a JMX replacement for the jsp version of the JVMInfo screen used by support to get a handle on JVM information. This information is environmental not operational and is used for support purposes. The jsp versions of the JVMInfo utilities are still provided, for backward compatibility, but now is also authorization controlled. JVMSystem - This is an implementation of the Java system MXBeans for use in monitoring. We provide our own implementation of the base Mbeans to save on creating another JMX configuration for internal monitoring and to provide a consistent interface across platforms for the MXBeans. This Mbean is disabled by default and can be enabled using the enableJVMSystemBeans operation. This Mbean allows for the monitoring of the ClassLoading, Memory, OperatingSystem, Runtime and the Thread MX beans. Refer to the Server Administration Guides provided with your product and the Technical Best Practices Whitepaper for information about individual statistics. The Web Application Server JMX monitoring allows greater visibility for monitoring and management of the Oracle Utilities Application Framework application from jconsole or any JSR160 compliant JMX browser or JMX console.

  • Five Key Trends in Enterprise 2.0 for 2011

    - by kellsey.ruppel(at)oracle.com
    We recently sat down with Andy MacMillan, an industry veteran and vice president of product management for Enterprise 2.0 at Oracle, to get his take on the year ahead in Enterprise 2.0 (E2.0). He offered us his five predictions about the ways he believes E2.0 technologies will transform business in 2011. 1. Forward-thinking organizations will achieve an unprecedented level of organizational awareness. Enterprise 2.0 and Web 2.0 technologies have already transformed the ways customers, employees, partners, and suppliers communicate and stay informed. But this year we are anticipating that organizations will go to the next step and integrate social activities with business applications to deliver rich contextual "activity streams." Activity streams are a new way for enterprise users to get relevant information as quickly as it happens, by navigating to that information in context directly from their portal. We don't mean syndicating social activities limited to a single application. Instead, we believe back-office systems will be combined with social media tools to drive how users make informed business decisions in brand new ways. For example, an account manager might log into the company portal and automatically receive notification that colleagues are closing business around a certain product in his market segment. With a single click, he can reach out instantly to these colleagues via social media and learn from their successes to drive new business opportunities in his own area. 2. Online customer engagement will become a high priority for CMOs. A growing number of chief marketing officers (CMOs) have created a new direct report called "head of online"--a senior marketing executive responsible for all engagements with customers and prospects via the Web, mobile, and social media. This new field has been dubbed "Web experience management" or "online customer engagement" by firms and analyst organizations. It is likely to rapidly increase demand for a host of new business objectives and metrics from Web content management solutions. As companies interface with customers more and more over the Web, Web experience management solutions will help deliver more targeted interactions to ensure increased customer loyalty while meeting sales and business objectives. 3. Real composite applications will be widely adopted. We expect organizations to move from the concept of a single "uber-portal" that encompasses all the necessary features to a more modular, component-based concept for composite applications. This approach is now possible as IT and power users are empowered to assemble new, purpose-built composite applications quickly from existing components. 4. Records management will drive ECM consolidation. We continue to see a significant shift in the approach to records management. Several years ago initiatives were focused on overlaying records management across a set of electronic repositories and physical storage locations. We believe federated records management will continue, but we also expect to see records management driving conversations around single-platform content management consolidation. 5. Organizations will demand ECM at extreme scale. We have already seen a trend within IT organizations to provide a common, highly scalable infrastructure to consolidate and support content and information needs. But as data sizes grow exponentially, ECM at an extreme scale is likely to spread at unprecedented speeds this year. This makes sense as regulations and transparency requirements rise. The model in which ECM and lightweight CMS systems provide basic content services such as check-in, update, delete, and search has converged around a set of industry best practices and has even been coded into new industry standards such as content management interoperability services. As these services converge and the demand for them accelerates, organizations are beginning to rationalize investments into a single, highly scalable infrastructure. Is your organization ready for Enterprise 2.0 in 2011? Learn more.

  • “NT AUTHORITY\ANONYMOUS LOGON” error in Windows 7 (ASP.NET & Web Service)

    - by Tony_Henrich
    I have an asp.net web app which works fine in Windows XP machine in a domain. I am porting it to a Windows 7 stand alone machine. The app uses a web service which makes a call to sql server. The web server (IIS 7.5) and SQL Server are on the same stand alone machine. I enabled Windows authentication for the website and web service. The web service uses a trusted connection connection string. The web service credentials uses System.Net.CredentialCache.DefaultCredentials. I noticed username, password and domainname are blank after the call! The webservice and web site use the 'Classic .NET AppPool' with NetworkServices identity. I am getting an exception "NT AUTHORITY\ANONYMOUS LOGON" in the database call in the web service. I am assuming it's related to the blank credentials. I am expecting ASPNET user to be the security token to the database. Why is this not happening? Did I miss a setting? (Usually this happens when sql server and web server are on two different machines in a domain, delegation & double hopping, but in my case everything is on a dev box)

  • Anti-Forgery Request Helpers for ASP.NET MVC and jQuery AJAX

    - by Dixin
    Background To secure websites from cross-site request forgery (CSRF, or XSRF) attack, ASP.NET MVC provides an excellent mechanism: The server prints tokens to cookie and inside the form; When the form is submitted to server, token in cookie and token inside the form are sent in the HTTP request; Server validates the tokens. To print tokens to browser, just invoke HtmlHelper.AntiForgeryToken():<% using (Html.BeginForm()) { %> <%: this.Html.AntiForgeryToken(Constants.AntiForgeryTokenSalt)%> <%-- Other fields. --%> <input type="submit" value="Submit" /> <% } %> This invocation generates a token then writes inside the form:<form action="..." method="post"> <input name="__RequestVerificationToken" type="hidden" value="J56khgCvbE3bVcsCSZkNVuH9Cclm9SSIT/ywruFsXEgmV8CL2eW5C/gGsQUf/YuP" /> <!-- Other fields. --> <input type="submit" value="Submit" /> </form> and also writes into the cookie: __RequestVerificationToken_Lw__= J56khgCvbE3bVcsCSZkNVuH9Cclm9SSIT/ywruFsXEgmV8CL2eW5C/gGsQUf/YuP When the above form is submitted, they are both sent to server. In the server side, [ValidateAntiForgeryToken] attribute is used to specify the controllers or actions to validate them:[HttpPost] [ValidateAntiForgeryToken(Salt = Constants.AntiForgeryTokenSalt)] public ActionResult Action(/* ... */) { // ... } This is very productive for form scenarios. But recently, when resolving security vulnerabilities for Web products, some problems are encountered. Specify validation on controller (not on each action) The server side problem is, It is expected to declare [ValidateAntiForgeryToken] on controller, but actually it has be to declared on each POST actions. Because POST actions are usually much more then controllers, this is a little crazy Problem Usually a controller contains actions for HTTP GET and actions for HTTP POST requests, and usually validations are expected for HTTP POST requests. So, if the [ValidateAntiForgeryToken] is declared on the controller, the HTTP GET requests become invalid:[ValidateAntiForgeryToken(Salt = Constants.AntiForgeryTokenSalt)] public class SomeController : Controller // One [ValidateAntiForgeryToken] attribute. { [HttpGet] public ActionResult Index() // Index() cannot work. { // ... } [HttpPost] public ActionResult PostAction1(/* ... */) { // ... } [HttpPost] public ActionResult PostAction2(/* ... */) { // ... } // ... } If browser sends an HTTP GET request by clicking a link: http://Site/Some/Index, validation definitely fails, because no token is provided. So the result is, [ValidateAntiForgeryToken] attribute must be distributed to each POST action:public class SomeController : Controller // Many [ValidateAntiForgeryToken] attributes. { [HttpGet] public ActionResult Index() // Works. { // ... } [HttpPost] [ValidateAntiForgeryToken(Salt = Constants.AntiForgeryTokenSalt)] public ActionResult PostAction1(/* ... */) { // ... } [HttpPost] [ValidateAntiForgeryToken(Salt = Constants.AntiForgeryTokenSalt)] public ActionResult PostAction2(/* ... */) { // ... } // ... } This is a little bit crazy, because one application can have a lot of POST actions. Solution To avoid a large number of [ValidateAntiForgeryToken] attributes (one for each POST action), the following ValidateAntiForgeryTokenAttribute wrapper class can be helpful, where HTTP verbs can be specified:[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)] public class ValidateAntiForgeryTokenWrapperAttribute : FilterAttribute, IAuthorizationFilter { private readonly ValidateAntiForgeryTokenAttribute _validator; private readonly AcceptVerbsAttribute _verbs; public ValidateAntiForgeryTokenWrapperAttribute(HttpVerbs verbs) : this(verbs, null) { } public ValidateAntiForgeryTokenWrapperAttribute(HttpVerbs verbs, string salt) { this._verbs = new AcceptVerbsAttribute(verbs); this._validator = new ValidateAntiForgeryTokenAttribute() { Salt = salt }; } public void OnAuthorization(AuthorizationContext filterContext) { string httpMethodOverride = filterContext.HttpContext.Request.GetHttpMethodOverride(); if (this._verbs.Verbs.Contains(httpMethodOverride, StringComparer.OrdinalIgnoreCase)) { this._validator.OnAuthorization(filterContext); } } } When this attribute is declared on controller, only HTTP requests with the specified verbs are validated:[ValidateAntiForgeryTokenWrapper(HttpVerbs.Post, Constants.AntiForgeryTokenSalt)] public class SomeController : Controller { // GET actions are not affected. // Only HTTP POST requests are validated. } Now one single attribute on controller turns on validation for all POST actions. Maybe it would be nice if HTTP verbs can be specified on the built-in [ValidateAntiForgeryToken] attribute, which is easy to implemented. Submit token via AJAX The browser side problem is, if server side turns on anti-forgery validation for POST, then AJAX POST requests will fail be default. Problem For AJAX scenarios, when request is sent by jQuery instead of form:$.post(url, { productName: "Tofu", categoryId: 1 // Token is not posted. }, callback); This kind of AJAX POST requests will always be invalid, because server side code cannot see the token in the posted data. Solution The tokens are printed to browser then sent back to server. So first of all, HtmlHelper.AntiForgeryToken() must be called somewhere. Now the browser has token in HTML and cookie. Then jQuery must find the printed token in the HTML, and append token to the data before sending:$.post(url, { productName: "Tofu", categoryId: 1, __RequestVerificationToken: getToken() // Token is posted. }, callback); To be reusable, this can be encapsulated into a tiny jQuery plugin:/// <reference path="jquery-1.4.2.js" /> (function ($) { $.getAntiForgeryToken = function (tokenWindow, appPath) { // HtmlHelper.AntiForgeryToken() must be invoked to print the token. tokenWindow = tokenWindow && typeof tokenWindow === typeof window ? tokenWindow : window; appPath = appPath && typeof appPath === "string" ? "_" + appPath.toString() : ""; // The name attribute is either __RequestVerificationToken, // or __RequestVerificationToken_{appPath}. tokenName = "__RequestVerificationToken" + appPath; // Finds the <input type="hidden" name={tokenName} value="..." /> from the specified. // var inputElements = $("input[type='hidden'][name='__RequestVerificationToken" + appPath + "']"); var inputElements = tokenWindow.document.getElementsByTagName("input"); for (var i = 0; i < inputElements.length; i++) { var inputElement = inputElements[i]; if (inputElement.type === "hidden" && inputElement.name === tokenName) { return { name: tokenName, value: inputElement.value }; } } return null; }; $.appendAntiForgeryToken = function (data, token) { // Converts data if not already a string. if (data && typeof data !== "string") { data = $.param(data); } // Gets token from current window by default. token = token ? token : $.getAntiForgeryToken(); // $.getAntiForgeryToken(window). data = data ? data + "&" : ""; // If token exists, appends {token.name}={token.value} to data. return token ? data + encodeURIComponent(token.name) + "=" + encodeURIComponent(token.value) : data; }; // Wraps $.post(url, data, callback, type). $.postAntiForgery = function (url, data, callback, type) { return $.post(url, $.appendAntiForgeryToken(data), callback, type); }; // Wraps $.ajax(settings). $.ajaxAntiForgery = function (settings) { settings.data = $.appendAntiForgeryToken(settings.data); return $.ajax(settings); }; })(jQuery); In most of the scenarios, it is Ok to just replace $.post() invocation with $.postAntiForgery(), and replace $.ajax() with $.ajaxAntiForgery():$.postAntiForgery(url, { productName: "Tofu", categoryId: 1 }, callback); // Token is posted. There might be some scenarios of custom token. Here $.appendAntiForgeryToken() is provided:data = $.appendAntiForgeryToken(data, token); // Token is already in data. No need to invoke $.postAntiForgery(). $.post(url, data, callback); And there are scenarios that the token is not in the current window. For example, an HTTP POST request can be sent by iframe, while the token is in the parent window. Here window can be specified for $.getAntiForgeryToken():data = $.appendAntiForgeryToken(data, $.getAntiForgeryToken(window.parent)); // Token is already in data. No need to invoke $.postAntiForgery(). $.post(url, data, callback); If you have better solution, please do tell me.

  • Oracle SOA Security for OUAF Web Services

    - by Anthony Shorten
    With the ability to use Oracle SOA Suite 11g with the Oracle Utilities Application Framework based products, an additional consideration needs to be configured to ensure correct integration. That additional consideration is security. By default, SOA Suite propagates any credentials from the calling application through to the interfacing applications. In most cases, this behavior is not appropriate as the calling application may use different credential stores and also some interfaces are “disconnected” from a calling application (for example, a file based load using the File Adapter). These situations require that the Web Service calls to the Oracle Utilities Application Framework based products have their own valid credentials. To do this the credentials must be attached at design time or at run time to provide the necessary credentials for the call. There are a number of techniques that can be used to do this: At design time, when integrating a Web Service from an Oracle Utilities Application Framework based product you can attach the security policy “oracle/wss_username_token_client_policy” in the composite.xml view. In this view select the Web Service you want to attach the policy to and right click to display the context menu and select “Configure WS Policies” and select the above policy from the list. If you are using SSL then you can use “oracle/wss_username_token_over_ssl_client_policy” instead. At design time, you can also specify the credential key (csf-key) associated with the above policy by selecting the policy and clicking “Edit Config Override Properties”. You name the key appropriately. Everytime the SOA components are deployed the credential configuration is also sent. You can also do this after deployment, or what I call at “runtime”, by specifying the policy and credential key in the Fusion Middleware Control. Refer to the Fusion Middleware Control documentation on how to do this. To complete the configuration you need to add a map and the key specified earlier to the credential store in the Oracle WebLogic instance used for Oracle SOA Suite. From Fusion Middleware Control, you do this by selecting the domain the SOA Suite is installed in a select “Credentials” from the context menu. You now need to add the credentials by adding the map “oracle.wsm.security” (the name is IMPORTANT) and creating a key with the necessary valid credentials. The example below added a key called “mdm.key”. The name I used is for example only. You can name the key anything you like as long as it corresponds to the key you specified in the design time component. Note: I used SYSUSER as an example credentials in the example, in real life you would use another credential as SYSUSER is not appropriate for production use. This key can be reused for other Oracle Utilities Application Framework Web Service integrations or you can use other keys for individual Web Service calls. Once the key is created and the SOA Suite components deployed the transactions should be able to be called as necessary. If you need to change the password for the credentials it can be done using the Fusion Middleware Control functionality.

  • Characteristics of a Web service that promote reusability and change

    Characteristics of a Web service that promote reusability and change:  Standardized Data Exchange Formats (XML, JSON) Standardized communication protocols (Soap, Rest) Promotes Loosely Coupled Systems  Standardized Data Exchange Formats (XML, JSON) XML W3.org defines Extensible Markup Language (XML) as a simplistic text format derived from SGML. XML was designed to solve challenges found in large-scale electronic publishing. In addition,  XML is playing an important role in the exchange of data primarily focusing on data exchange on the web. JSON JavaScript Object Notation (JSON) is a human-readable text-based standard designed for data interchange. This format is used for serializing and transmitting data over a network connection in a structured format. The primary use of JSON is to transmit data between a server and web application. JSON is an alternative to XML. Standardized communication protocols (Soap, Rest) Soap W3Scools.com defines SOAP as a simple XML-based protocol. This protocol lets applications exchange data over HTTP.  SOAP provides a way to communicate between applications running on different operating systems, with different technologies and programming languages. Rest In 2007, Stefan Tilkov defines Representational State Transfer (REST) as a set of principles that outlines how Web standards are supposed to be used.  Using REST in an application will ensure that it exploits the Web’s architecture to its benefit. Promotes Loosely Coupled Systems “Loose coupling as an approach to interconnecting the components in a system or network so that those components, also called elements, depend on each other to the least extent practicable. Coupling refers to the degree of direct knowledge that one element has of another.” (TechTarget.com, 2007) “Loosely coupled system can be easily broken down into definable elements. The extent of coupling in a system can be measured by mapping the maximum number of element changes that can occur without adverse effects. Examples of such changes include adding elements, removing elements, renaming elements, reconfiguring elements, modifying internal element characteristics and rearranging the way in which elements are interconnected.” (TechTarget.com, 2007) References: W3C.

  • How to wrap console utils in webserver

    - by Alex Brown
    I have a big dataset (100Mbs/day) and a bunch of console a TCL/TK tools to view it - I want to turn it into a web app that I can build, and others can maintain. In long: my group runs simulations yielding 100s of Mbs of data daily, in multiple (mostly but not only) text forms. We have a bunch of scripts and tools, mostly old school 1990's style stuff requiring a 5-button mouse, as well as lots of ad-hoc scripts that engineers build out of frustration every month or so. These produces UIs, graphs, spreadsheets (various sizes), logs, event histories etc. I want to replace (or at least supplement) the xwindows / console style UI with a web-based one, so I need the following properties: pleasant to program can wrap existing command-line tools in separate views (I don't need to scrape GUIs or anything) as I port logic from the existing scripts I can create a modularised and pleasant codebase to replace it I can attach a web-ui to navigate between views - each view is likely to contain keys which might make sense to view in another I am new to building systems that have logic on the back-end and front-end of a web-server. from that point of view, they do this: backend wraps old-school executables, constructs calls into them and them takes the output and wraps it up, niceifies it and delivers it to the web client. For instance the tool might generate a number of indexed images (per invocation) which I might deliver all at once or on-demand. May (probably) need to to heavy stats on some sources. frontend provides navigation connecting multiple views, performs requests from one view for data from another (or self to self), etc. Probably will have some views with a lot of interactivity. Can people please point me towards viable solutions for this? I know it's a bit of an open question so as answers come in I hope to refine the spec until we have a good match. I guess I expect to see answers like "RoR!" "beans!" "Scala!" but please give an indication of why those are a good fit; I know nothing! I got bumped off SO for asking an open-ended question, so sorry if its OT here too (let me know). I take the policy that I use the best/closest matched language for a project but most of my team are extremely low level (ie pipeline stages and CDyn) so I don't have the peer group to know where to start.

  • Load and Web Performance Testing using Visual Studio Ultimate 2010-Part 3

    - by Tarun Arora
    Welcome back once again, in Part 1 of Load and Web Performance Testing using Visual Studio 2010 I talked about why Performance Testing the application is important, the test tools available in Visual Studio Ultimate 2010 and various test rig topologies, in Part 2 of Load and Web Performance Testing using Visual Studio 2010 I discussed the details of web performance & load tests as well as why it’s important to follow a goal based pattern while performance testing your application. In part 3 I’ll be discussing Test Result Analysis, Test Result Drill through, Test Report Generation, Test Run Comparison, Asp.net Profiler and some closing thoughts. Test Results – I see some creepy worms! In Part 2 we put together a web performance test and a load test, lets run the test to see load test to see how the Web site responds to the load simulation. While the load test is running you will be able to see close to real time analysis in the Load Test Analyser window. You can use the Load Test Analyser to conduct load test analysis in three ways: Monitor a running load test - A condensed set of the performance counter data is maintained in memory. To prevent the results memory requirements from growing unbounded, up to 200 samples for each performance counter are maintained. This includes 100 evenly spaced samples that span the current elapsed time of the run and the most recent 100 samples.         After the load test run is completed - The test controller spools all collected performance counter data to a database while the test is running. Additional data, such as timing details and error details, is loaded into the database when the test completes. The performance data for a completed test is loaded from the database and analysed by the Load Test Analyser. Below you can see a screen shot of the summary view, this provides key results in a format that is compact and easy to read. You can also print the load test summary, this is generated after the test has completed or been stopped.         Analyse the load test results of a previously run load test – We’ll see this in the section where i discuss comparison between two test runs. The performance counters can be plotted on the graphs. You also have the option to highlight a selected part of the test and view details, drill down to the user activity chart where you can hover over to see more details of the test run.   Generate Report => Test Run Comparisons The level of reports you can generate using the Load Test Analyser is astonishing. You have the option to create excel reports and conduct side by side analysis of two test results or to track trend analysis. The tools also allows you to export the graph data either to MS Excel or to a CSV file. You can view the ASP.NET profiler report to conduct further analysis as well. View Data and Diagnostic Attachments opens the Choose Diagnostic Data Adapter Attachment dialog box to select an adapter to analyse the result type. For example, you can select an IntelliTrace adapter, click OK and open the IntelliTrace summary for the test agent that was used in the load test.   Compare results This creates a set of reports that compares the data from two load test results using tables and bar charts. I have taken these screen shots from the MSDN documentation, I would highly recommend exploring the wealth of knowledge available on MSDN. Leaving Thoughts While load testing the application with an excessive load for a longer duration of time, i managed to bring the IIS to its knees by piling up a huge queue of requests waiting to be processed. This clearly means that the IIS had run out of threads as all the threads were busy processing existing request, one easy way of fixing this is by increasing the default number of allocated threads, but this might escalate the problem. The better suggestion is to try and drill down to the actual root cause of the problem. When ever the garbage collection runs it stops processing any pages so all requests that come in during that period are queued up, but realistically the garbage collection completes in fraction of a a second. To understand this better lets look at the .net heap, it is divided into large heap and small heap, anything greater than 85kB in size will be allocated to the Large object heap, the Large object heap is non compacting and remember large objects are expensive to move around, so if you are allocating something in the large object heap, make sure that you really need it! The small object heap on the other hand is divided into generations, so all objects that are supposed to be short-lived are suppose to live in Gen-0 and the long living objects eventually move to Gen-2 as garbage collection goes through.  As you can see in the picture below all < 85 KB size objects are first assigned to Gen-0, when Gen-0 fills up and a new object comes in and finds Gen-0 full, the garbage collection process is started, the process checks for all the dead objects and assigns them as the valid candidate for deletion to free up memory and promotes all the remaining objects in Gen-0 to Gen-1. So in the future when ever you clean up Gen-1 you have to clean up Gen-0 as well. When you fill up Gen – 0 again, all of Gen – 1 dead objects are drenched and rest are moved to Gen-2 and Gen-0 objects are moved to Gen-1 to free up Gen-0, but by this time your Garbage collection process has started to take much more time than it usually takes. Now as I mentioned earlier when garbage collection is being run all page requests that come in during that period are queued up. Does this explain why possibly page requests are getting queued up, apart from this it could also be the case that you are waiting for a long running database process to complete.      Lets explore the heap a bit more… What is really a case of crisis is when the objects are living long enough to make it to Gen-2 and then dying, this is definitely a high cost operation. But sometimes you need objects in memory, for example when you cache data you hold on to the objects because you need to use them right across the user session, which is acceptable. But if you wanted to see what extreme caching can do to your server then write a simple application that chucks in a lot of data in cache, run a load test over it for about 10-15 minutes, forcing a lot of data in memory causing the heap to run out of memory. If you get to such a state where you start running out of memory the IIS as a mode of recovery restarts the worker process. It is great way to free up all your memory in the heap but this would clear the cache. The problem with this is if the customer had 10 items in their shopping basket and that data was stored in the application cache, the user basket will now be empty forcing them either to get frustrated and go to a competitor website or if the customer is really patient, give it another try! How can you address this, well two ways of addressing this; 1. Workaround – A x86 bit processor only allows a maximum of 4GB of RAM, this means the machine effectively has around 3.4 GB of RAM available, the OS needs about 1.5 GB of RAM to run efficiently, the IIS and .net framework also need their share of memory, leaving you a heap of around 800 MB to play with. Because Team builds by default build your application in ‘Compile as any mode’ it means the application is build such that it will run in x86 bit mode if run on a x86 bit processor and run in a x64 bit mode if run on a x64 but processor. The problem with this is not all applications are really x64 bit compatible specially if you are using com objects or external libraries. So, as a quick win if you compiled your application in x86 bit mode by changing the compile as any selection to compile as x86 in the team build, you will be able to run your application on a x64 bit machine in x86 bit mode (WOW – By running Windows on Windows) and what that means is, you could use 8GB+ worth of RAM, if you take away everything else your application will roughly get a heap size of at least 4 GB to play with, which is immense. If you need a heap size of more than 4 GB you have either build a software for NASA or there is something fundamentally wrong in your application. 2. Solution – Now that you have put a workaround in place the IIS will not restart the worker process that regularly, which means you can take a breather and start working to get to the root cause of this memory leak. But this begs a question “How do I Identify possible memory leaks in my application?” Well i won’t say that there is one single tool that can tell you where the memory leak is, but trust me, ‘Performance Profiling’ is a great start point, it definitely gets you started in the right direction, let’s have a look at how. Performance Wizard - Start the Performance Wizard and select Instrumentation, this lets you measure function call counts and timings. Before running the performance session right click the performance session settings and chose properties from the context menu to bring up the Performance session properties page and as shown in the screen shot below, check the check boxes in the group ‘.NET memory profiling collection’ namely ‘Collect .NET object allocation information’ and ‘Also collect the .NET Object lifetime information’.    Now if you fire off the profiling session on your pages you will notice that the results allows you to view ‘Object Lifetime’ which shows you the number of objects that made it to Gen-0, Gen-1, Gen-2, Large heap, etc. Another great feature about the profile is that if your application has > 5% cases where objects die right after making to the Gen-2 storage a threshold alert is generated to alert you. Since you have the option to also view the most expensive methods and by capturing the IntelliTrace data you can drill in to narrow down to the line of code that is the root cause of the problem. Well now that we have seen how crucial memory management is and how easy Visual Studio Ultimate 2010 makes it for us to identify and reproduce the problem with the best of breed tools in the product. Caching One of the main ways to improve performance is Caching. Which basically means you tell the web server that instead of going to the database for each request you keep the data in the webserver and when the user asks for it you serve it from the webserver itself. BUT that can have consequences! Let’s look at some code, trust me caching code is not very intuitive, I define a cache key for almost all searches made through the common search page and cache the results. The approach works fine, first time i get the data from the database and second time data is served from the cache, significant performance improvement, EXCEPT when two users try to do the same operation and run into each other. But it is easy to handle this by adding the lock as you can see in the snippet below. So, as long as a user comes in and finds that the cache is empty, the user locks and starts to get the cache no more concurrency issues. But lets say you are processing 10 requests per second, by the time i have locked the operation to get the results from the database, 9 other users came in and found that the cache key is null so after i have come out and populated the cache they will still go in to get the results again. The application will still be faster because the next set of 10 users and so on would continue to get data from the cache. BUT if we added another null check after locking to build the cache and before actual call to the db then the 9 users who follow me would not make the extra trip to the database at all and that would really increase the performance, but didn’t i say that the code won’t be very intuitive, may be you should leave a comment you don’t want another developer to come in and think what a fresher why is he checking for the cache key null twice !!! The downside of caching is, you are storing the data outside of the database and the data could be wrong because the updates applied to the database would make the data cached at the web server out of sync. So, how do you invalidate the cache? Well if you only had one way of updating the data lets say only one entry point to the data update you can write some logic to say that every time new data is entered set the cache object to null. But this approach will not work as soon as you have several ways of feeding data to the system or your system is scaled out across a farm of web servers. The perfect solution to this is Micro Caching which means you cache the query for a set time duration and invalidate the cache after that set duration. The advantage is every time the user queries for that data with in the time span for which you have cached the results there are no calls made to the database and the data is served right from the server which makes the response immensely quick. Now figuring out the appropriate time span for which you micro cache the query results really depends on the application. Lets say your website gets 10 requests per second, if you retain the cache results for even 1 minute you will have immense performance gains. You would reduce 90% hits to the database for searching. Ever wondered why when you go to e-bookers.com or xpedia.com or yatra.com to book a flight and you click on the book button because the fare seems too exciting and you get an error message telling you that the fare is not valid any more. Yes, exactly => That is a cache failure! These travel sites or price compare engines are not going to hit the database every time you hit the compare button instead the results will be served from the cache, because the query results are micro cached, its a perfect trade-off, by micro caching the results the site gains 100% performance benefits but every once in a while annoys a customer because the fare has expired. But the trade off works in the favour of these sites as they are still able to process up to 30+ page requests per second which means cater to the site traffic by may be losing 1 customer every once in a while to a competitor who is also using a similar caching technique what are the odds that the user will not come back to their site sooner or later? Recap   Resources Below are some Key resource you might like to review. I would highly recommend the documentation, walkthroughs and videos available on MSDN. You can always make use of Fiddler to debug Web Performance Tests. Some community test extensions and plug ins available on Codeplex might also be of interest to you.

  • Zscaler. Certs, cookies, and port 80 traffic

    - by 54's_lol
    So I work at HQ for a large company that shall remain nameless. We use Zscaler and I had to roll out a 2048 cert per zscaler's request. People around me at work dont understand the technology and think that the cert's are what is allowing internet connectivity. From my understanding(and please chime in) is the cookie located C:\Users\$$$$$$4$$\AppData\Roaming\Macromedia\Flash Player#SharedObjects\Q3JQJQJV\gateway.zscaler.net\zscaler.swf here that gets created when you provide your creds the first time you use the browser. The cert's are just simply a way of inspecting the SSL traffic as zscaler had no way of doing this before without them. They are essentially using the classic MITM attack to parse your SSL traffic. Gmail is smart enough to recognize this as you get a warning. My question is this, is there a product or service that I can use to verify my web browser when at home(I.E. off company network) isn't still getting routed to zscaler's cloud? If i do a tracert that will work fine. It's the port 80 and 443 web traffic zscaler and my company is after. I would like to verify that when I'm off their premise that my web traffic is using only my isp and the path to whatever content I'm searching for. Do the cert's i'm pushing and browser authentication do something behind the curtain that forces web traffic to get routed to zscaler? I searched quite a bit and would very much like to know if I'm ever off company scrutiny. I do know zscaler offers the service to force the scenario im asking about. Can I prove how my web traffic is getting routed? Thanks for any insight. I've been a fan for a long time and your guy's kung fu is very strong:-)

  • Disable click action after letting up a mouse wheel hold scroll in Chrome browser

    - by Joe Miller
    I apologize in advance for the confusing title, not sure what the best way to describe this action is. Basically, I am holding down the mouse wheel and then moving the mouse itself up and down to scroll (not actually rotating the mouse wheel forward or backward). This is often the most convenient way to scroll for me. Unfortunately, when I scroll in this way, and then let up the mouse wheel again, it performs a click action, so if the arrow happens to land on a link when I let up the mouse wheel, I end up inadvertently clicking that link. How can I prevent the mouse from performing a click action when I use the mouse wheel to scroll by holding it down and then letting it up when I am done scrolling? It seems like this is only happening in the Chrome browser. Thanks! Windows 7, Chrome Browser, Logitech Mouse

  • Kerberos SSO browser integration?

    - by MrZombie
    I'm installing a bunch of web apps for the office, and one of the wants would be Kerberos-managed SSO. Now, I have found some information on the matter, and I wondered, what browsers integrate Kerberos SSO? Of course I could just use the underlying web app to authenticate in case of lack of Kerberos capability, which is exactly the plan, but I'd like to know which browsers would work for that, so I can plan ahead and decide if it's even worth it to do that, which I believe it would considering that one of the web apps I'm implementing will be an ERP.

  • How to tunnel all traffic through Tor?

    - by HappyDeveloper
    All I want is be able to use flash and javascript while using Tor (I don't intend to use it for torrents) Normally, using flash with Tor is not recommended because firefox plugins run outside of the sandbox, so the browser's proxy settings don't apply to them, and can reveal your real IP. But I think it should be possible to also redirect flash to the same socket as the browser, and block the other outgoing ports just in case. Any ideas on how to do this?

  • Chrome browser caching

    - by Kyle B.
    I do a lot of development on my local machine and would like to start using Chrome, however I cannot seem to do a hard-refresh (ctrl+f5) or any other key combination to get my browser to forcibly refresh all content @ http://localhost. I change projects frequently in IIS and this presents a problem because I see stylesheet and image data from my previous project with no way to get this page to reload without forcibly dumping all cache data from the settings menu. Is there another key combination I am missing, or is there a place I can (on a site by site basis) turn off caching? I prefer not to have to clear out my temporary files in the browser settings as I switch projects frequently. Thanks, Kyle

  • Java 7 update 6 installation fails on Windows 7 when Chrome is default browser

    - by ali1234
    I am configuring a brand new Lenovo U410 system with Windows 7 Home Premium for a user. I received the system direct from the shop. As part of the configuration I installed Java using the online installer. This worked correctly. Later, due to a mistake I made, I needed to restore the system to factory default. The factory default FORMATS C:\ and puts back (supposedly) the exact factory configuration. However, after doing this, I was no longer able to install Java successfully using the same method I used before. Now, whenever I attempt to use the online Java installer, the following happens. First of all, a window always appears "Welcome to Java", "Downloading Java Installer...". After short time this window disappears and then one of three things happens: The very first time I do this after doing a factory reset, I get a Windows error report, which contains this information: Application Name: JavaSetup7u5.exe Application Version: 7.0.50.6 Application Timestamp: 4feacd84 Fault Module Name: JavaIC.dll Fault Module Version: 9.9.9.9 Fault Module Timestamp: 4f2343d6 Exception Offset: 000052cb Exception Code: c0000417 Exception Data: 00000000 OS Version: 6.1.7600.2.0.0.768.3 Locale ID: 1033 Additional Information 1: 773c Additional Information 2: 773cd78cf06816f8246f359fa270f3bb Additional Information 3: f51a Additional Information 4: f51aaea7d22f36fa9e3a626b5a5cd1c3 2. Subsequent runs produce either this error message: "Error: Java(TM) installer - Downloaded file C:\Users\\AppData\Local\Temp\fx-runtime.exe is corrupt." or Nothing happens at all. I Believe this is a red herring. Running the installer again causes a different error because the files were downloaded and the installer crashed before it could clean up. This isn't the actual problem, as when this happens the installer deletes the downloaded files, and then when you run it for the third time, it downloads everything again and does the javaic.dll crash. I suspect the downloader is appending to the existing files or something, causing the corruption. I have tried all of the above as Administrator and as a normal user. I have tried reseting the system to factory defaults several times. I have tried downloading with Chrome and Internet Explorer 9. I have tried uninstalling all anti-virus software and disabling the windows firewall entirely. The only thing which makes a difference is running the installer in Windows XP compatibility mode, which allows the installation to complete. I know I can workaround this error by using the offline installer so please don't post that as an answer. I am looking for an explanation of the root cause. Additionally, if I use the offline installer, the updater does not work. The updater also does not work if I install in XP mode. The updater fails because it works by just downloading the newest online setup and running it. Also remember that the installers are digitally signed. The signitures verify correctly so there is no way in hell that this is caused by corrupted downloads. Some theories I have: The Java setup files on java.com actually changed in between the first successful install and my later attempts. Seems unlikely as none of the version numbers have changed. However, I have seen a couple of reports of this error which showed up in the past 24 hours. This looks like the most likely explanation right now: http://www.oracle.com/us/corporate/press/1735645 - Oracle released 7 update 6 two days ago. Careful inspection of the installers reveal that they are in fact attempting to download .6, not .5 as the download page claims. Not actually correct. Only the update tool tries to install 7u6. The online installer still tries 7u5. However, 7u6 being released two days ago is too much of a coincidence to ignore. Update: The 7u6 online installer is available from Oracle technetwork. It crashes in exactly the same way. The factory reset software uses GMT-8 and I am on GMT-1. As a result, after factory reset, any software which cares to check would think that the system was restored 7 hours in the future, due to Window's awful policy of storing local time in the system clock. This could be confusing a certificate check or similar. Update: I discovered that this does cause Windows Update to fail. The workaround, setting the clock back before starting factory reset, does not enable Java to install correctly. The factory reset image isn't really the same as what is installed in the main partition when you buy the system. Naughty Lenovo. The installer appears to crash while installing or displaying something to do with the Ask.com toolbar. That seems to be what javaic.dll does. Microsoft Tuesday was the 14th. Some update in that could be causing this. However, I'm factory reseting the machine every time, so unless the patches get slipstreamed into the recovery image, or there is some mechanism by which they get silently installed even if updates are disabled, then I don't see how this can be the cause. Major breakthrough: The default browser on Lenovo systems is Google Chrome. I noticed that the JavaIC.dll "sponsor check" actually does a check on your default browser in order to decide which sponsor ad to display. Normally that would get you the Ask toolbar on IE9. But that toolbar doesn't work on Chrome, and so the installer tries to display a different ad. The different ad is what causes the crash. Changing the default browser to IE9 allows the installer to run correctly. So this looks like a genuine bug in the sponsor ad code in the installer, caused by a combination of Google Chrome default browser and not being in the US. (Installer also checks your location using IP geolocation service and displays different ads based on that.)

  • IIS7, different ports for websites but no portnumber in the browser

    - by Queensheep
    I have a windows server 2008 with IIS7 with 4 websites. In DNS I have 4 different URLs which point to the IP of the server. I configured each web site with the site bindings: website1: hostname: url1, port: 80, IP-Adresse: the adress of the server website2: hostname: url2, port: 80, IP-Adresse: the adress of the server The result is, that from the client, I can browse with all the 4 URLs to the specified web sites and everything is fine. Then I changed in IIS the port of the websites, so that website1 now uses port 8080, website2 uses port 8081, and so on. Now I have to use the browser with the url and the portnumber (like URL:8080). Is there a possibility, to configured the websites with different portnumbers but not to use the portnumbers in the browser?

  • Getting HAPROXY to redirect http to https in users browser session

    - by Jon
    We are currently using a Internet cloud provider to host our SaaS platform. The platform consists of a Firewall - Cloud Provider SLB - - Apache Web Server - HAPROXY SLB - Liferay Platform We have had to use HAPROXY because of an issue with the cloud providers SLB that meant we were unable to use it for load balancing the Liferay platform applications. I have implemented HAPROXY in our secure tier and that seems to do the trick of load balancing the requests quite adequately. However during testing we encountered a functional issue whereby selecting a sub-menu from the web portal resulted in the application hanging, using an http analyser we saw that the request being passed back to the users browser was in http, from discussing this with the software vendor it transpires that the Liferay application has some hard-coded http links, and that other customers have worked around this by using physical NLB's such as F5 and redirecting the http traffic to https. The entry in the HAPROXY logs reads: haproxy[2717]: haproxy[2717]: <Apache Web Agent>:37957 [11/Apr/2013:08:07:00.128] http-uapi uapi/<ServerName> 0/0/0/9/10 200 4912 - - ---- 4/2/1/2/0 0/0 "GET /servicedesk/controller?docommand=renderradform&!key=esd_sfb001_frm_feedback_forms_list&isportalintegratedmode=true&USR=joe.bloggs%40gmail.com&_dc=1365667773097&redirecturl=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_SFB001_FRM_FEEDBACK_FORMS_LIST%26isportalintegratedmode%3Dtrue&sso_token=ALiYv2UqzLsAhSw1ZchRDlCHlq44Bhj9&ONERROR=%2Fweb%2Fjsp%2Fapps%2Fportal-integration-error.jsp&itype=login&slicetoken=NW51O%242aRo%2C_Zz%2476P_9DTtnFmz6%28bhk&AUTOFORWARDURL=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_SFB001_FRM_FEEDBACK_FORMS_LIST%26isportalintegratedmode%3Dtrue&LOGINPAGE=https%3A%2F%2F<FQDN of Web Portal>%2Fweb%2F4732cf01-82c3-4bc5-b6c9-552253e672cf%2Fworkflow-tools&appid=1&!uid=1&!redownloadToken=7.0.3.1.1363611301.0&userlocale=en_US&!datechanged=2012-05-18%2015:05:31.38 HTTP/1.1" :37957 [11/Apr/2013:08:07:00.128] http-uapi uapi/<ServerName> 0/0/0/9/10 200 4912 - - ---- 4/2/1/2/0 0/0 "GET /servicedesk/controller?docommand=renderradform&!key=esd_sfb001_frm_feedback_forms_list&isportalintegratedmode=true&USR=joe.bloggs%40gmail.com&_dc=1365667773097&redirecturl=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_SFB001_FRM_FEEDBACK_FORMS_LIST%26isportalintegratedmode%3Dtrue&sso_token=ALiYv2UqzLsAhSw1ZchRDlCHlq44Bhj9&ONERROR=%2Fweb%2Fjsp%2Fapps%2Fportal-integration-error.jsp&itype=login&slicetoken=NW51O%242aRo%2C_Zz%2476P_9DTtnFmz6%28bhk&AUTOFORWARDURL=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_SFB001_FRM_FEEDBACK_FORMS_LIST%26isportalintegratedmode%3Dtrue&LOGINPAGE=https%3A%2F%2F<FQDN of Web Portal>%2Fweb%2F4732cf01-82c3-4bc5-b6c9-552253e672cf%2Fworkflow-tools&appid=1&!uid=1&!redownloadToken=7.0.3.1.1363611301.0&userlocale=en_US&!datechanged=2012-05-18%2015:05:31.38 HTTP/1.1" The corresponding HTTP browser entry shows: http://<FQDN of ServiceDesk>/servicedesk/controller?docommand=renderradform&!key=esd_org019_frm_contact_list&isportalintegratedmode=true&USR=joe.bloggs%40gmail.com&_dc=1365665987887&redirecturl=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_ORG019_FRM_CONTACT_LIST%26isportalintegratedmode%3Dtrue&sso_token=3NxsXYORMPp32SwL8ftVUCMH2QdWLH82&ONERROR=%2Fweb%2Fjsp%2Fapps%2Fportal-integration-error.jsp&itype=login&slicetoken=NW51O%242aRo%2C_Zz%2476P_9DTtnFmz6%28bhk&AUTOFORWARDURL=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_ORG019_FRM_CONTACT_LIST%26isportalintegratedmode%3Dtrue&LOGINPAGE=https%3A%2F%2F<FQDN of Web Portal>>%2Fweb%2F4732cf01-82c3-4bc5-b6c9-552253e672cf%2Fapplication-setup&appid=1&!uid=1&!redownloadToken=7.0.3.1.1363611301.0&userlocale=en_US&!datechanged=2012-10-26%2019:00:25.08 From reading through the forums and other sites it looks like we should be use to use HAPROXY to redirect the traffic to https, but try as I might I cant get it to work.

  • Local links ( in browsers ) on *nix systems

    - by meder
    On Windows I can access files directly from the browser ( or at least I have it configured currently, forget if it was native like this ) with the file:// protocol, so I can access files from say the C drive. I'm wondering what the equivalent would be to accessing my files from the browser, if at all possible on a *nix system such as Debian.

  • What to do for a 1 million concurrent web application? [duplicate]

    - by Amit Singh
    This question already has an answer here: How do you do load testing and capacity planning for web sites? 3 answers There are few things that I would like to know here. What server configuration do I need. And if I am deploying it on EC2 how many VMs do I need and what should be their configuration. What options do I have to do a load testing for 1 million concurrent users. Any pointer to (for php) how to code or what to keep in mind for such application. This is for sure that I don't exactly know what to ask because this is my first application on this scale. But one thing is clear that this application should pass a load test of 1 million concurrent request.
