Is there an established or defined best practice for source control branching between development and production builds?

- by Matthew Patrick Cashatt

Thanks for looking. I struggled in how to phrase my question, so let me give an example in hopes of making more clear what I am after: I currently work on a dev team responsible for maintaining and adding features to a web application. We have a development server and we use source control (TFS). Each day everyone checks in their code and when the code (running on the dev server) passes our QA/QC program, it goes to production. Recently, however, we had a bug in production which required an immediate production fix. The problem was that several of us developers had code checked in that was not ready for production so we had to either quickly complete and QA the code, or roll back everything, undo pending changes, etc. In other words, it was a mess. This made me wonder: Is there an established design pattern that prevents this type of scenario. It seems like there must be some "textbook" answer to this, but I am unsure what that would be. Perhaps a development branch of the code and a "release-ready" or production branch of the code?

Skip CodedUI Tests, use Selenium for Web Automation

- by Aligned

Originally posted on: http://geekswithblogs.net/Aligned/archive/2013/10/31/skip-codedui-tests-use-selenium-for-web-automation.aspxI recently joined a team that was using Agile Methodologies to create a new product. They have a working beta product after 10 or so 2 week sprints and already had UI’s that had changed several times as they went through iterations of their UI. As a result, the QA team was falling behind with automated tests and I was tasked to help them catch up and expand their tests. The project is a website. I heard many complaints about how hard it is to work with CodedUI (writing our own code, not relying on the recorder as we wanted re-usable and more maintainable code) then it took me 4+ hours to fix one issue. It was hard to traverse the key and debugging the objects with breakpoints… I said out loud “there has to be a better way or a framework the uses jQuery to run through the tests.” Plus it seemed really slow (wait… finding the object … wait… start putting in text…). Plus some tests would randomly fail on the test agents (using the test settings and an automated build, they are run on VMs using Microsoft test agents). Enough complaining. Selenium to the rescue (mostly). The lead QA guy decided to try it out and we haven’t turned back. We are now running tests in Chrome and Firefox and they run a lot faster. We had IE running to, but some of the tests were running fine locally, but hanging on the test agents. I’ll add some hints and lessons learned in a later post.

I've scanned my new webserver and I'm surprised to find that in the results there's programs that I never installed.

Hi all, I am trying to a perform build automation on one of web application projects built using VS 2008. The _PublishedWebSites contains two folders: Web and Deploy. I just want the TFS 2008 to generate only the Deploy Folder and Not the Web Folder.

Load Testing Linux Virtual Server

- by Anubhav Agarwal

I have configured a Linux virtual network with following configuration 172.17.6.112- VIP 172.17.6.111- Linux Director | |----------172.17.6.113 --- Real Server 1 |----------172.17.6.114 --- Real Server 2 I am using direct routing technique. I am unable to test my LVS network. Are there some good scripts/softwares available for load testing. I am running apache2.0 service on them. I came across with testlvs on the internet but am unable to understand its documentation. Are there more simpler ones I want to test the response time of server using various scheduling algorithms .

Changes to JBoss web.xml have no effect

- by sixtyfootersdude

I just added this to my web.xml on my JBOSS server. But it had no effect. I am still allowed to connect to ports that do not use bi-directional certificate exchange. Anyone have an ideas?  <security-constraint>  <web-resource-collection>   <web-resource-name> Entire Application </web-resource-name>  <url-pattern> /* </url-pattern> </web-resource-collection>  <user-data-constraint>          <transport-guarantee> CONFIDENTIAL </transport-guarantee> </user-data-constraint> </security-constraint> <login-config>    <auth-method> CLIENT-CERT </auth-method> </login-config> Update Actually it appears that I have made an error in my original posting. The web.xml does block users from connecting to the webservice using http (port C below). However users are still allowed to connect to ports that do not force users to authenticate themselves (port B). I think that users should be able to connect to port A (it has clientAuth="true") but I dont think that people should be able to connect to port B (it has clientAuth="false"). Excerpt from server.xml <Connector port="<A>" ... SSLEnabled="true" ... scheme="https" secure="true" clientAuth="true" keystoreFile="... .keystore" keystorePass="pword" truststoreFile="... .keystore" truststorePass="pword" sslProtocol="TLS"/> <Connector port="<B>" ...

Does unit testing lead to premature generalization (specifically in the context of C++)?

- by Martin

Preliminary notes I'll not go into the distinction of the different kinds of test there are, there are already a few questions on these sites regarding that. I'll take what's there and that says: unit testing in the sense of "testing the smallest isolatable unit of an application" from which this question actually derives The isolation problem What is the smallest isolatable unit of a program. Well, as I see it, it (highly?) depends on what language you are coding in. Micheal Feathers talks about the concept of a seam: [WEwLC, p31] A seam is a place where you can alter behavior in your program without editing in that place. And without going into the details, I understand a seam -- in the context of unit testing -- to be a place in a program where your "test" can interface with your "unit". Examples Unit test -- especially in C++ -- require from the code under test to add more seams that would be strictly called for for a given problem. Example: Adding a virtual interface where non-virtual implementation would have been sufficient Splitting -- generalizing(?) -- a (smallish) class further "just" to facilitate adding a test. Splitting a single-executable project into seemingly "independent" libs, "just" to facilitate compiling them independently for the tests. The question I'll try a few versions that hopefully ask about the same point: Is the way that Unit Tests require one to structure an application's code "only" beneficial for the unit tests or is it actually beneficial to the applications structure. Is the generalization code need to exhibit to be unit-testable useful for anything but the unit tests? Does adding unit tests force one to generalize unnecessarily? Is the shape unit tests force on code "always" also a good shape for the code in general as seen from the problem domain? I remember a rule of thumb that said don't generalize until you need to / until there's a second place that uses the code. With Unit Tests, there's always a second place that uses the code -- namely the unit test. So is this reason enough to generalize?

How to do integrated testing?

- by Enthusiastic Programmer

So I have been reading up on a lot of books surrounding testing. But all the books I've read have the same flaws. They will all tell you the definitions of testing. But I have not found a single book that will guide you into integration testing (or pretty much anything higher then unit testing). Is integration testing that elusive or am I reading the wrong books? I'm a hands on person, so I would appreciate it if someone could help me with a simple program: Let's say you need to make some sort of calculation program that calculates something (doesn't matter what) and exports it to *.txt file. Let's assume we use the Model View Controller design principle. And one class for the actual calculating which you'll use in the model and one for writing the textfile. So: View = Controller = Model = CalculationClass, FileClass So for unittesting: You'd test the calculationClass, I'd personally focus most of my unit tests there. And less time on unit testing the view/controller/FileClass. I personally wouldn't see the use of unittesting those unless you want a really robust program. Integration testing: Now this is where I run into a wall. What would I have to test to call it an integration test? I could stub the view and feed the controller data which it would pass on to the model and so forth. And then check what the view gets back in the end. But ... Couldn't I just run the (in this case small) program then and test it manually? Would this be considered a integration test too, or does it have to be automated? Also, can I check multiple items to see if they are correct? I cannot seem to find any book that offers a hands on approach to methods of integration testing.

Asp.net web service: Problems accessing without www

- by MysterM

I have a Asp.net web service running on www.domain.com/Service.svc that I connect to using jQuery from my asp.net website. Everything works perfect if the user access my website with www.domain.com. But if the user uses only domain.com I get error: There was no channel actively listening at 'http://domain.com/Service.svc/get?date=2010-10-09'. This is often caused by an incorrect address URI. Ensure that the address to which the message is sent matches an address on which a service is listening. In my web.config I use the serviceHostingEnvironment tag to get the service running on my webhost (it doesn't work otherwise). Maybe this is what causes the error? Here is my system.serviceModel in web.config (I had some problems setting up the web service so that's why my web.config might be a bit messy: <system.serviceModel> <behaviors> <endpointBehaviors> <behavior name="ServiceAspNetAjaxBehavior"> <enableWebScript /> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="ServiceBehavior"> <serviceDebug includeExceptionDetailInFaults="true" /> </behavior> </serviceBehaviors> </behaviors> <serviceHostingEnvironment aspNetCompatibilityEnabled="true"> <baseAddressPrefixFilters> <add prefix="http://www.domain.com"/> </baseAddressPrefixFilters> </serviceHostingEnvironment> <services> <service behaviorConfiguration="ServiceBehavior" name="Service"> <endpoint address="" behaviorConfiguration="ServiceAspNetAjaxBehavior" binding="webHttpBinding" bindingConfiguration="ServiceBinding" contract="Service" /> </service> </services> <bindings> <webHttpBinding> <binding name="ServiceBinding" maxBufferPoolSize="1000000" maxReceivedMessageSize="1000000"> <readerQuotas maxDepth="1000000" maxStringContentLength="1000000" maxArrayLength="1000000" maxBytesPerRead="1000000" maxNameTableCharCount="1000000" /> </binding> </webHttpBinding> </bindings> </system.serviceModel> How can I make it possible for my users to access my webservice also when using only domain.com?

New Features in ASP.NET Web API 2 - Part I

- by dwahlin

I’m a big fan of ASP.NET Web API. It provides a quick yet powerful way to build RESTful HTTP services that can easily be consumed by a variety of clients. While it’s simple to get started using, it has a wealth of features such as filters, formatters, and message handlers that can be used to extend it when needed. In this post I’m going to provide a quick walk-through of some of the key new features in version 2. I’ll focus on some two of my favorite features that are related to routing and HTTP responses and cover additional features in a future post. Attribute Routing Routing has been a core feature of Web API since it’s initial release and something that’s built into new Web API projects out-of-the-box. However, there are a few scenarios where defining routes can be challenging such as nested routes (more on that in a moment) and any situation where a lot of custom routes have to be defined. For this example, let’s assume that you’d like to define the following nested route: /customers/1/orders This type of route would select a customer with an Id of 1 and then return all of their orders. Defining this type of route in the standard WebApiConfig class is certainly possible, but it isn’t the easiest thing to do for people who don’t understand routing well. Here’s an example of how the route shown above could be defined: public static class WebApiConfig { public static void Register(HttpConfiguration config) { config.Routes.MapHttpRoute( name: "CustomerOrdersApiGet", routeTemplate: "api/customers/{custID}/orders", defaults: new { custID = 0, controller = "Customers", action = "Orders" } ); config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); GlobalConfiguration.Configuration.Formatters.Insert(0, new JsonpFormatter()); } } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } With attribute based routing, defining these types of nested routes is greatly simplified. To get started you first need to make a call to the new MapHttpAttributeRoutes() method in the standard WebApiConfig class (or a custom class that you may have created that defines your routes) as shown next: public static class WebApiConfig { public static void Register(HttpConfiguration config) { // Allow for attribute based routes config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); } } Once attribute based routes are configured, you can apply the Route attribute to one or more controller actions. Here’s an example: [HttpGet] [Route("customers/{custId:int}/orders")] public List<Order> Orders(int custId) { var orders = _Repository.GetOrders(custId); if (orders == null) { throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.NotFound)); } return orders; } This example maps the custId route parameter to the custId parameter in the Orders() method and also ensures that the route parameter is typed as an integer. The Orders() method can be called using the following route: /customers/2/orders While this is extremely easy to use and gets the job done, it doesn’t include the default “api” string on the front of the route that you might be used to seeing. You could add “api” in front of the route and make it “api/customers/{custId:int}/orders” but then you’d have to repeat that across other attribute-based routes as well. To simply this type of task you can add the RoutePrefix attribute above the controller class as shown next so that “api” (or whatever the custom starting point of your route is) is applied to all attribute routes: [RoutePrefix("api")] public class CustomersController : ApiController { [HttpGet] [Route("customers/{custId:int}/orders")] public List<Order> Orders(int custId) { var orders = _Repository.GetOrders(custId); if (orders == null) { throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.NotFound)); } return orders; } } There’s much more that you can do with attribute-based routing in ASP.NET. Check out the following post by Mike Wasson for more details. Returning Responses with IHttpActionResult The first version of Web API provided a way to return custom HttpResponseMessage objects which were pretty easy to use overall. However, Web API 2 now wraps some of the functionality available in version 1 to simplify the process even more. A new interface named IHttpActionResult (similar to ActionResult in ASP.NET MVC) has been introduced which can be used as the return type for Web API controller actions. To return a custom response you can use new helper methods exposed through ApiController such as: Ok NotFound Exception Unauthorized BadRequest Conflict Redirect InvalidModelState Here’s an example of how IHttpActionResult and the helper methods can be used to cleanup code. This is the typical way to return a custom HTTP response in version 1: public HttpResponseMessage Delete(int id) { var status = _Repository.DeleteCustomer(id); if (status) { return new HttpResponseMessage(HttpStatusCode.OK); } else { throw new HttpResponseException(HttpStatusCode.NotFound); } } With version 2 we can replace HttpResponseMessage with IHttpActionResult and simplify the code quite a bit: public IHttpActionResult Delete(int id) { var status = _Repository.DeleteCustomer(id); if (status) { //return new HttpResponseMessage(HttpStatusCode.OK); return Ok(); } else { //throw new HttpResponseException(HttpStatusCode.NotFound); return NotFound(); } } You can also cleanup post (insert) operations as well using the helper methods. Here’s a version 1 post action: public HttpResponseMessage Post([FromBody]Customer cust) { var newCust = _Repository.InsertCustomer(cust); if (newCust != null) { var msg = new HttpResponseMessage(HttpStatusCode.Created); msg.Headers.Location = new Uri(Request.RequestUri + newCust.ID.ToString()); return msg; } else { throw new HttpResponseException(HttpStatusCode.Conflict); } } This is what the code looks like in version 2: public IHttpActionResult Post([FromBody]Customer cust) { var newCust = _Repository.InsertCustomer(cust); if (newCust != null) { return Created<Customer>(Request.RequestUri + newCust.ID.ToString(), newCust); } else { return Conflict(); } } More details on IHttpActionResult and the different helper methods provided by the ApiController base class can be found here. Conclusion Although there are several additional features available in Web API 2 that I could cover (CORS support for example), this post focused on two of my favorites features. If you have .NET 4.5.1 available then I definitely recommend checking the new features out. Additional articles that cover features in ASP.NET Web API 2 can be found here.

Advanced tasks using Web.Config transformation

- by dcadenas

Does anyone know if there is a way to "transform" specific sections of values instead of replacing the whole value or an attribute? For example, I've got several appSettings entries that specify the Urls for different webservices. These entries are slightly different in the dev environment than the production environment. Some are less trivial than others  <appSettings> <add key="serviceName1_WebsService_Url" value="http://wsServiceName1.dev.domain.com/v1.2.3.4/entryPoint.asmx" /> <add key="serviceName2_WebsService_Url" value="http://ma1-lab.lab1.domain.com/v1.2.3.4/entryPoint.asmx" /> </appSettings>  <appSettings> <add key="serviceName1_WebsService_Url" value="http://wsServiceName1.prod.domain.com/v1.2.3.4/entryPoint.asmx" /> <add key="serviceName2_WebsService_Url" value="http://ws.ServiceName2.domain.com/v1.2.3.4/entryPoint.asmx" /> </appSettings> So far, I know I can do something like this in the Web.Release.Config: <add xdt:Locator="Match(key)" xdt:Transform="SetAttributes(value)" key="serviceName1_WebsService_Url" value="http://wsServiceName1.prod.domain.com/v1.2.3.4/entryPoint.asmx" /> <add xdt:Locator="Match(key)" xdt:Transform="SetAttributes(value)" key="serviceName2_WebsService_Url" value="http://ws.ServiceName2.domain.com/v1.2.3.4/entryPoint.asmx" /> However, everytime the Version for that webservice is updated, I would have to update the Web.Release.Config as well, which defeats the purpose of simplfying my web.config updates. I know I could also split that URL into different sections and update them independently, but I rather have it all in one key. I've looked through the available web.config Transforms but nothings seems to be geared towars what I am trying to accomplish. These are the websites I am using as a reference: Vishal Joshi's blog, MSDN Help, and Channel9 video Any help would be much appreciated! -D

Threading calls to web service in a web service - (.net 2.0)

- by Ryan Ternier

Got a question regarding best practices for doing parallel web service calls, in a web service. Our portal will get a message, split that message into 2 messages, and then do 2 calls to our broker. These need to be on separate threads to lower the timeout. One solution is to do something similar to (pseudo code): XmlNode DNode = GetaGetDemoNodeSomehow(); XmlNode ENode = GetAGetElNodeSomehow(); XmlNode elResponse; XmlNode demResponse; Thread dThread = new Thread(delegate { //Web Service Call GetDemographics d = new GetDemographics(); demResponse = d.HIALRequest(DNode); }); Thread eThread = new Thread(delegate { //Web Service Call GetEligibility ge = new GetEligibility(); elResponse = ge.HIALRequest(ENode); }); dThread.Start(); eThread.Start(); dThread.Join(); eThread.Join(); //combine the resulting XML and return it. //Maybe throw a bit of logging in to make architecture happy Another option we thought of is to create a worker class, and pass it the service information and have it execute. This would allow us to have a bit more control over what is going on, but could add additional overhead. Another option brought up would be 2 asynchronous calls and manage the returns through a loop. When the calls are completed (success or error) the loop picks it up and ends. The portal service will be called about 50,000 times a day. I don't want to gold plate this sucker. I'm looking for something light weight. The services that are being called on the broker do have time out limits set, and are already heavily logged and audited, so I'm not worried on that part. This is .NET 2.0 , and as much as I would love to upgrade I can't right now. So please leave all the goodies of 2.0 out please.

Get XML-RPC (Andorid - PHP) web service different params type

- by Jovan

Hi, I want to create XML-RPC web service for Andorid (client) - PHP (Server) communication I create XML-RPC PHP web service server using this tutorial: http://articles.sitepoint.com/article/own-web-service-php-xml-rpc/5 For andorid client web service I use this project: http://code.google.com/p/android-xmlrpc/ server and client communication is OK, but I have problem with getting params from andorid client to php server. From andorid client I send two params (first integer and second float number) Object[] params = { 3, 3.6f, }; method.call(params); , but I don't know how to handle this parameters in php server?? in php server there is some function , but with only one param ($news_id): function news_viewNewsItem ( $news_id ) { /* Define the query to fetch the news item */ $query = "SELECT * FROM kd_xmlrpc_news WHERE news_id = '" . $news_id . "'"; $sql = mysql_query ( $query ); if ( $result = mysql_fetch_array ( $sql ) ) { /* Extract the variables for sending in our server response */ $news_item['news_id'] = $result['news_id']; $news_item['date'] = XMLRPC_convert_timestamp_to_iso8601( mysql_datetime_to_timestamp( $result['date'] ) ); $news_item['title'] = $result['title']; $news_item['full_desc'] = $result['full_desc']; $news_item['author'] = $result['author']; /* Respond to the client with the news item */ XMLRPC_response(XMLRPC_prepare($news_item), KD_XMLRPC_USERAGENT); } else { /* If there was an error, respond with a fault code instead */ XMLRPC_error("1", "news_viewNewsItem() error: Unable to read news:" . mysql_error(), KD_XMLRPC_USERAGENT); } } In server.py file there is functions for every method but I dont know how to write in php server: def add(self, x, y): print print "input x=%s, y=%s" % (str(x), str(y)) sum = x + y print "output", sum print return sum Can some one help me with code , and tell me how to handle various types from client to server??

my web service works locally but, not when it is deployed

- by rogdawg

When I deploy my web service, I get the following error: There is no build provider registered for the extension '.svc'. You can register one in the section in machine.config or web.config. Make sure is has a BuildProviderAppliesToAttribute attribute which includes the value 'Web' or 'All'. I found one thread (http://forums.asp.net/t/1228638.aspx) that suggested a solution but, I can not get it to work. If I make the changes to my web config file as suggested in the thread, I then get a configuration error. One odd thing is that, if I check the machine.config file on my machine, located at C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.config, I don't see any of the config settings described in the thread. As a matter of fact, there is no mention of "compilation" or "buildProviders" at all. The on-line documents I have found regarding BuildProviderAppliesToAttribute have not been of any help. Thanks in advance for any advice you can give. Here is my entire config file listing: <?xml version="1.0"?>

How to document an existing small web site (web application), inside and out?

- by Ricket

We have a "web application" which has been developed over the past 7 months. The problem is, it was not really documented. The requirements consisted of a small bulleted list from the initial meeting 7 months ago (it's more of a "goals" statement than software requirements). It has collected a number of features which stemmed from small verbal or chat discussions. The developer is leaving very soon. He wrote the entire thing himself and he knows all of the quirks and underlying rules to each page, but nobody else really knows much more than the user interface side of it; which of course is the easy part, as it's made to be intuitive to the user. But if someone needs to repair or add a feature to it, the entire thing is a black box. The code has some minimal comments, and of course the good thing about web applications is that the address bar points you in the right direction towards fixing a problem or upgrading a page. But how should the developer go about documenting this web application? He is a bit lost as far as where to begin. As developers, how do you completely document your web applications for other developers, maintainers, and administrative-level users? What approach do you use, where do you start, do you have a template? An idea of magnitude: it uses PHP, MySQL and jQuery. It has about 20-30 main (frontend) files, along with about 15 included files and a couple folders of some assets. So overall it's a pretty small application. It interfaces with 7 MySQL tables, each one well-named, so I think the database end is pretty self-explanatory. There is a config.inc.php file with definitions of consts like the MySQL user details, some from/to emails, and URLs which PHP uses to insert into emails and pages (relative and absolute paths, basiecally). There is some AJAX via jQuery. Please comment if there is any other information that would help you help me and I will be glad to edit it in.

Virtualbox HTTP load testing, host CPU overload issues

- by aschuler

I'm doing HTTP load testing benchmarks (using Apache Benchmark and Siege) on a small Java EE 1.7.0 / Tomcat 7.0.26 application running on a Debian Squeeze 6.0.4 x64 virtualized with Virtualbox 4.1.8. The computer host is Ubuntu 11.10 x64. I've modified those parameters in the Tomcat server.xml : <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="200000" redirectPort="8443" acceptCount="2000" maxThreads="150" minSpareThreads="50" /> The application executed on the server takes around 300ms. This app is running well until a certain amount of concurrent connections like those one : ab -n 500 -c 150 http://xx.xx.xx.xx:8080/myapp/ ab -n 1000 -c 50 http://xx.xx.xx.xx:8080/myapp/ siege -b -c 100 -r 20 http://xx.xx.xx.xx:8080/myapp/ A lot of socket connection timed out happens and this completly overload the host processor (but the CPU load inside the VM is normal). Doing an htop on the host, i can see that the Virtualbox processus is running under 300% CPU and never come down even after the load test is finished. (I've allocated 4 processors to the VM, if I allocate only one processor, CPU load goes under 100%). Restarting Tomcat don't do anything, i'm forced to restart the whole VM. I've tryed to launch those ab/siege commands locally on the VM and everything goes well. I first thought it was related to a linux network limit as explained here: Running some benchmarks using ab, and tomcat starts to really slow down So I've modified those TCP parameters : echo 15 > /proc/sys/net/ipv4/tcp_fin_timeout echo 30 > /proc/sys/net/ipv4/tcp_keepalive_intvl echo 1 > /proc/sys/net/ipv4/tcp_tw_recycle echo 1 > /proc/sys/net/ipv4/tcp_tw_reuse It seems to be better, but it continues to overload the host CPU and output socket connections time out at a certain amount of concurrent connections. I'm wondering if this is not related to how Virtualbox handles external concurrent connections.

Load Testing a Security/Gateway Appliance

- by Joel Coel

In a couple weeks I will load testing a security/gateway appliance. We're a small residential college, and that "residential" means the traffic moving through the appliance is a bit like the Wild West. We have everything from Facebook to World of Warcraft, BitTorrent to Netflix, or Halo to YouTube... basically anything you might find in the home of a high-school or college aged person. Somewhere in there some real academic work gets done as well. We rely on our current appliance for traffic shaping, antivirus, malware filtering, intrusion detection on our servers, logging and abuse reporting, and even some content filtering. All this puts a decent load when we have students around, and I'm concerned about the ability of the new candidate to keep up. On paper it should handle things, but I'm worried. Prior experience is that vendors greatly over-report what an appliance can handle. The product also includes a licensed session limit, and I'm also worried that just a few misbehaving students could unwittingly bring us to that limit and cause service disruptions. I need to know this will work for our campus in order to commit to it. Going a performance level higher in that product takes the pricing way out of line with what we expect and have done in the past. What I need is a good way to load test this guy. My problem is that our current level of summer traffic is less than one percent of what it will be when students come back just six weeks from now. Any ideas on how to really stress this thing and see what it can do, in a way that will give me some clear ideas o. How that will scale for our campus? For the curious, I'm looking at a Watchguard 515, but it could be anything. If I were evaluating a competitor, I'd ask the same question.

Dividing web.config into multiple files in asp.net

- by Jalpesh P. Vadgama

When you are having different people working on one project remotely you will get some problem with web.config, as everybody was having different version of web.config. So at that time once you check in your web.config with your latest changes the other people have to get latest that web.config and made some specific changes as per their local environment. Most of people who have worked things from remotely has faced that problem. I think most common example would be connection string and app settings changes. For this kind of situation this will be a best solution. We can divide particular section of web.config into the multiple files. For example we could have separate ConnectionStrings.config file for connection strings and AppSettings.config file for app settings file. Most of people does not know that there is attribute called ‘configSource’ where we can define the path of external config file and it will load that section from that external file. Just like below. <configuration> <appSettings configSource="AppSettings.config"/> <connectionStrings configSource="ConnectionStrings.config"/> </configuration> And you could have your ConnectionStrings.config file like following. <connectionStrings> <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-WebApplication1-20120523114732;Integrated Security=True" providerName="System.Data.SqlClient" /> </connectionStrings> Same way you have another AppSettings.Config file like following. <appSettings> <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" /> <add key="ValidationSettings:UnobtrusiveValidationMode" value="WebForms" /> </appSettings> That's it. Hope you like this post. Stay tuned for more..

Fixing the Model Binding issue of ASP.NET MVC 4 and ASP.NET Web API

- by imran_ku07

Introduction: Yesterday when I was checking ASP.NET forums, I found an important issue/bug in ASP.NET MVC 4 and ASP.NET Web API. The issue is present in System.Web.PrefixContainer class which is used by both ASP.NET MVC and ASP.NET Web API assembly. The details of this issue is available in this thread. This bug can be a breaking change for you if you upgraded your application to ASP.NET MVC 4 and your application model properties using the convention available in the above thread. So, I have created a package which will fix this issue both in ASP.NET MVC and ASP.NET Web API. In this article, I will show you how to use this package. Description: Create or open an ASP.NET MVC 4 project and install ImranB.ModelBindingFix NuGet package. Then, add this using statement on your global.asax.cs file, using ImranB.ModelBindingFix; Then, just add this line in Application_Start method, Fixer.FixModelBindingIssue(); // For fixing only in MVC call this //Fixer.FixMvcModelBindingIssue(); // For fixing only in Web API call this //Fixer.FixWebApiModelBindingIssue(); . This line will fix the model binding issue. If you are using Html.Action or Html.RenderAction then you should use Html.FixedAction or Html.FixedRenderAction instead to avoid this bug(make sure to reference ImranB.ModelBindingFix.SystemWebMvc namespace). If you are using FormDataCollection.ReadAs extension method then you should use FormDataCollection.FixedReadAs instead to avoid this bug(make sure to reference ImranB.ModelBindingFix.SystemWebHttp namespace). The source code of this package is available at github. Summary: There is a small but important issue/bug in ASP.NET MVC 4. In this article, I showed you how to fix this issue/bug by using a package. Hopefully you will enjoy this article too.

Sharing one static ip for both ftp and www service

- by user11496

Trying to figure out how to update the Zone record and configure webserver so that one application on the webserver is accessible by public. I'm completely not good at NS/DNS/NAT/firewall/routing/port forwarding/networking etc. "faraday" is the intranet name. Everyone within local network can access all applications hosted on "faraday". Hostname for webserver is "www", FTP server is "ftpserver". Both servers running RHEL4 OS. The goal is to allow anyone outside the company network (public) to access only one of the many applications on "faraday". Hope somebody can help me with some of the questions below, if not all. From zoneedit record, the static IP is used by FTP now. Can I use the same existing static IP - 219.95.10.100, for web service? Currently anyone who enter "http://www.abc.com.my" will be directed to "http://www.abc.com". I don't want this to change. Currently, no one else, except employee on local network, can access "faraday" web pages. How to configure so that when anyone type "http://thisapp.abc.com.my" on their web browser, the url will lead them to "http://faraday/thisapp" (application folder is /var/www/html/thisapp on RHEL4 web server). If possible, how to set the URL will continue to show "http://thisapp.abc.com.my" instead of "http://faraday/thisapp" How to limit/restrict user (those who are not from local network) so they only have access to "http://thisapp.abc.com.my", but not "http://faraday" or "http://faraday/anotherapp", etc. What's the configuration changes needed in /etc/httpd.conf on web server? Company domain name is "abc.com.my". Following is the zone records on www.zoneedit.com. Subdomain Type IP sdsl A 219.95.10.100 ftp CNAME sdsl.abc.com.my @ NS ns3.zoneedit.com @ NS ns7.zoneedit.com WebForward record: New Domain Destination Cloaked www.abc.com.my http://www.abc.com N On my local DNS server, there are 2 zone files: abc.com.my and pnmy.abc.com. > cat abc.com.my.zone ftp CNAME ftp.pnmy.abc.com. sdsl A 219.95.10.100 > cat pnmy.abc.com.zone ftp CNAME ftpserver ftpserver A 172.16.5.1 faraday CNAME www www A 172.16.5.2

How to Deploy Visual Web Developer Express to GoDaddy

- by Randy

I have finished the programming on my first web site using Microsoft Visual Web Developer 2010 Express. I have copied all of the files to the GoDaddy server, but the site still displays "Coming Soon". I spoke with their tech support who tell me that there is no "index" file. I used the "Copy Web Site" function in VWD to move all the files over via FTP, so I know of no other files that should be copied. Nor do I understand what they are referring to as in "index" file. Has anybody else had this problem? Can anybody help me to figure out why this isn't working? Thanks! Randy

Unit testing Jade

- by Strawberry

Hi, What techniques and design strategies have people used to aid in unit testing Jade applications? In particular, how do people typically go about testing Behaviours - which are tightly coupled to the Agent instance and the Jade environment? I'm aware of the JadeMX project, but this appears to be geared more towards system testing - in particular the message exchange between collaborating agents. Thanks.
