• Good Guide For Web App Security?

  - by QAH

  Hello! I am pretty good on making web applications and I know how to transfer data to and from client/server, etc. I need some help though learning how to make the data exchanges more secure. That is the reason why I feel kind of scared to publish any web app I make. I wanted to know what are some good guides to help you understand and learn how to secure data transfer with your web application? Things like better authentication for example and making better logins. You can post any suggestion, but just for your information, I mainly code my web apps with Javascript and PHP. Also, I transfer my data using JSON or XML. Thanks a lot

• Visual Studio 2005 "Add Web Deployment Project..." not showing up for web application projects.

  - by Joe Sands

  I downloaded the Web Deployment Project plug-in for Visual Studio 2005. I installed it. I have a project that I am working on that is a Web Application Project. The Add Web Deployment Project Build menu selection is not in the Build Menu or Solution Explorer. If I create a raw test Web Site Project, the menu item magically appears. Is this by design or am I missing something. Also, I am completely up to date on all the VS 2005 updates.

• desktop shortcut icon not showing in web setup project

  - by davsan

  i've created a web setup project and i wanted it to create a desktop shortcut to the web application (ex: http://localhost/xx/yy.aspx). up to this point it was pretty easy: i created a shortcut (doesnt matter where), gave it the url i wanted, added this to the User's Desktop special folder of my web setup project, and it was placed on the desktop after the installation. but then i wanted to display my custom shortcut icon. i set the icon of the shortcut i've created on my file system. then i re-included this to the setup project. however after the installation the shortcut kept showing the default IE icon again. (i tried these on windows 2003 server, on win xp the shortcut showed up iconless) after some trials i found another way: i recreated an iconless shortcut on my file system, opened my web setup project, included this shortcut and my icon to Web Application Folder under File System on Target Machine, then clicked on User's Desktop, right clicked on the right hand side blank area, selected Create New Shortcut and chose the shortcut i've just added. Then under User's Desktop i clicked on the newly created shortcut, opened the Properties window and set its Icon property to my included icon. These steps solved it all both on 2003 server and win xp. Though this wasnt really a question i wanted to share it anyways because it was quite annoying.

• Clean Web.Config file in Asp.NET 4.0?

  - by Braveyard

  Okay, I am wondering having clear web.config file could be good but you know some shared web hosting companies don't allow us to touch things like machine.config and etc. So If a lot of things have been moved onto machine.config, then will we be allowed to change things like we used to through web.config file.

• Can't access web service when connected to the network :: HTTP 407

  - by Ian

  Hi All, I have a console application that communicates with a web service. Both of them are on the same machine. When I am accessing the web service with the LAN disabled, it connects without a problem. But if the LAN is enabled and connected to our office network, I receive this error: "HTTP 407 Proxy Authentication required - The ISA Server requires authorization to fulfill the request. Access to the Web Proxy service is denied." We've been hunting the source of the problem for three days now. We have tried everything that we can think of. Any ideas what's causing the problem? Additional notes: - The machine is in a Workgroup setup but with DNS suffix (computer.local). When accessing the web service, we type the address as "http://machine.computer.local/service.asmx" I talked to the IT guys and they said that we don't have an ISA server installed There is no "proxy" set in IE. The machine is in mint condition.

• Web Services: more frequent "small" calls, or less frequent "big" calls

  - by Klay

  In general, is it better to have a web application make lots of calls to a web service getting smaller chunks of data back, or to have the web app make fewer calls and get larger chunks of data? In particular, I'm building a Silverlight app that needs to get large amounts of data back from the server in response to a query created by a user. Each query could return anywhere from a few hundred records to a few thousand. Each record has around thirty fields of mostly decimal-type data. I've run into the situation before where the payload size of the response exceeded the maximum allowed by the service. I'm wondering whether it's better (more efficient for the server/client/web service) to cut this payload vertically--getting all values for a single field with each call--or horizontally--getting batches of complete records with each call. Or does it matter?

• Deliver files from a web server from outside the web app

  - by Ankur

  Is there anyway to serve a file from a web server through the web, that is not within the web application. I am using Tomcat and a Java servlets based application. I don't want to put the files within the webapp because they are several 100GB and I will have to replace them every time I update the WAR if I put them inside it.

• SQL CLR Stored Procedure and Web Service

  - by Nathan

  I am current working on a task in which I am needing to call a method in a web service from a CLR stored procedure. A bit of background: Basically, I have a task that requires ALOT of crunching. If done strictly in SQL, it takes somewhere around 30-45 mins to process. If I pull the same process into code, I can get it complete in seconds due to being able to optimize the processing so much more efficiently. The only problem is that I have to have this process set as an automated task in SQL Server. In that vein, I have exposed the process as a web service (I use it for other things as well) and want the SQL CLR sproc to consume the service and execute the code. This allows me to have my automated task. The problem: I have read quite a few different topics regarding how to consume a web service in a CLR Sproc and have done so effectivly. Here is an example of what I have followed. http://blog.hoegaerden.be/2008/11/11/calling-a-web-service-from-sql-server-2005/ I can get this example working without any issues. However, whenever I pair this process w/ a Web Service method that involves a database call, I get the following exceptions (depending upon whether or not I wrap in a try / catch): Msg 10312, Level 16, State 49, Procedure usp_CLRRunDirectSimulationAndWriteResults, Line 0 .NET Framework execution was aborted. The UDP/UDF/UDT did not revert thread token. or Msg 6522, Level 16, State 1, Procedure MyStoredProc , Line 0 A .NET Framework error occurred during execution of user defined routine or aggregate 'MyStoredProc': System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.EnvironmentPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. System.Security.SecurityException: at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) at System.Security.CodeAccessPermission.Demand() at System.Net.CredentialCache.get_DefaultCredentials() at System.Web.Services.Protocols.WebClientProtocol.set_UseDefaultCredentials(Boolean value) at MyStoredProc.localhost.MPWebService.set_UseDefaultCredentials(Boolean Value) at MyStoredProclocalhost.MPWebService..ctor() at MyStoredProc.StoredProcedures.MyStoredProc(String FromPostCode, String ToPostCode) I am sure this is a permission issue, but I can't, for the life of me get it working. I have attempted using impersonation in the CLR sproc and a few other things. Any suggestions? What am I missing?

• Google OpenID changes?!?!?

  - by Andrea

  I'm trying to implement OpenId login for a web application. Whenever new user who logs in via OpenId I create a new user on the sustem, and among the data I store their openid URL, so that next time they login with that user. I'm testing this with my Gmail OpenID, and the problem is that everytime I do this, Google sends a different openid URL, that is, https://www.google.com/accounts/o8/id?id=SomethingThatChangesFromTimeToTime Of course I'm then not able to tell wheter this is or not a new user. I'm a bit puzzled: shouldn't the openid identifier always remain the same?

• Problems with WiX and Visual Studio web deployment project

  - by Valeriu

  Hello, I want to create an .MSI package from a web deployment project in Visual Studio 2008. Now we want to use continuous integration and we would need the .MSI package build in the nightly builds. Till now we used standard Visual Studio Web Setup project, but this is not compatible with the MSBuild. So we decided to use WiX. The problem is that I have not found any good tutorial/documentation about this. Is there a way to do a WiX installer package from a web deployment project? If yes, how? Also, I tried to use heat.exe to create the XML for the WiX project .wxs file, but it seems that heat.exe doesn't recognize the web deployment project format. Thank you for your responses. Regards, V.

• Web Hosting Plan

  - by Laith J

  I'm looking for a new web hosting service, currently I'm using GoDaddy's Economy plan but it offers only PHP server-side scripting. For my next project it looks like I'm gonna need to use Java. Currently I pay ~60 USD per year for both the domain and the web hosting plan. Anyone knows of a web hosting service that supports Java and isn't much more expensive than this? Thanks, God bless

• Why does 'localhost' in web references cause SocketExceptions?

  - by Sam

  I have two .net web services deployed to the same IIS server using SSL, one that references the other. If I set that web reference to 'localhost', some calls fail with this exception: System.Web.Services.Protocols.SoapException: Server was unable to process request. --- System.Net.WebException: Unable to connect to the remote server --- System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it If I set it to the actual machine name, it works. Why?

• Is wordpress a good platform for webapp development?

  - by darlinton

  I am planning a webapp to control bank paying orders. In a quick review, the user goes online and creates a payment order. This order goes to other people that pays it and register the payment on the system. The system keeps track of all the payments, keeping the account balance up-to-date. The system needs a login system, bank integration, and to support at some point thousands of clients. We can find articles on the web about the benefits of using wordpress platform to build webapps. However, I could not find discussion with counterarguments to user wordpress. As the platform the most important choice in webapp project, I would to know more about the pitfalls and harms for choosing wordpress. The question is: What are the benefits and harms for choosing wordpress as a development platform for a webapp that need to be integrated with other system (backend systems) and to handle thousands of users (does it scale up?)?

• What is the length of time to send a list of 200,000 integers from a client's browser to an internet

  - by indiehacker

  Over the connections that most people in the USA have in their homes, what is the approximate length of time to send a list of 200,000 integers from a client's browser to an internet sever (say Google app engine)? Does it change much if the data is sent from an iPhone? How does the length of time increase as the size of the integer list increases (say with a list of a million integers) ? Context: I wasn't sure if I should write code to do some simple computations and sorting of such lists for the browser in javascript or for the server in python, so I wanted to explore this issue of how long it takes to send the output data from a browser to a server over the web in order to help me decide where (client's browser or app engine server) is the best place for such computations to be processed.

• ASP.NET - Web Application, UserControls and NullReferenceExceptions

  - by Echilon

  I have a web application, which works fine if I include my user controls with <%@ Register TagPrefix="mine" TagName="MyUC1" Src="~/UserControls/MyUc1.ascx" %> <%@ Register TagPrefix="mine" TagName="MyUC2" Src="~/UserControls/MyUc2.ascx" %> But I need to use the namespace due to needing to integrate with Umbraco. When I replace the register declaration with: <%@ Register TagPrefix="mine" Namespace="MyAssembly.UserControls" Assembly="MyAssembly"%> I get a null reference exception in the UserControl's Page_Load event (which references an ASP.NET control which is used by the UserControl itself. I find this pretty bizarre, but I've found very little information on how to fix it.

• Auto Encryption of web.config connection string

  - by Klaas Jan

  I want to encrypt the connection string in web.config, the problem is each time a developer changes the connection string in web.config and publishes, it needs to be encrypted every time in the web server. Is there any way that the connection string can encrypted automatically every time someone publishes it? Note :- All of us work on our local machines other than the server. So encryption using local machine key is not an option.

• WSDL for other protocols different than SOAP?

  - by SDReyes

  From wikipedia: The Web Services Description Language (WSDL, pronounced 'wiz-d?l') is an XML-based language that provides a model for describing Web services. But in most cases, I found that WSDL is used in conjunction with SOAP. but as far as I know, if the WSDL is a language to describe web services. there should be possible to describe another kind of web services different from SOAP. is this possible? any examples? Thanks!

• VS2010 Clean Web.configs - not updating

  - by cw

  Hello, I'm messing around with MVC 2.0 on VS2010 and am having an issue getting the clean web config feature working. Basically in my Web.debug.config I have <connectionStrings xdt:Transform="Replace"> <add name="ApplicationServices" connectionString="Server=localhost;Database=SITE_DB;User ID=dbuser;Password=P@ssw0rd;Trusted_Connection=False;" /> </connectionStrings> and in my Web.config I have <connectionStrings> <add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient" /> </connectionStrings> When I run the site in debug mode, I'd expect that xdt:Transform="Replace" would replace the entire connectionStrings section with what is in the Web.debug.config. Am I assuming wrong? Or am I doing something else incorrect. Not much info posted around this and I'd figure I'd ask you guys.

• How to protect web site against hackers?

  - by Adi barda

  Hi Guys, Like everyone of us, I have my own dreams about developing the next cool product that will be adopted by many users and become industry standard. Surprisingly, I find that the most challenging task is to keep my website up & running. My site is being hacked again and again no matter what I do - I blocked the FTP connections, changed the Joomla (CMS) database table names, installed all latest patches and what not. The web site supports the product (over 1800 users now...) by generating licenses, support forums, documentation, galleries etc. The product which is a winforms application cannot be marketed without this web site. My question: Do you have any innovative idea about securing joomla based web sites or what is the best secured web hosting you know. currently i'm hosting my site at ixwebhosting and i like them very much but obviously i can't do any serious marketing being hacked over and over again Thank you very much, Adi Barda
