  .net asp.net httphandler ihttphandler
  I’m working on an IHttpHandler implementation which will handle all *.gif files. The Handler itself will have code in it to check whether the *.gif files are requested from a certain URL. If this is the case, some customer logic should be performed to put a customer gif in the response.But I don’t know what to do when a regular gif is requested. This should be processed as normal. How do I do this?

  asp.net asp.net-mvc-2 ihttphandler ihttpasynchandler
  I made a custom handler that derives from MvcHandler. I have my routes using a custom RouteHandler that returns my new handler for GetHttpHandler(), and I override ProcessRequest() in my custom handler. The call to GetHttpHandler is triggering a breakpoint and my handler’s constructor is definitely being called, but BeginProcessRequest() is being called on the base MvcHandler instead of ProcessRequest(). Why are the async methods being called when I haven’t done anything to call them? I don

  asp.net web-config ihttphandler
  I had an ASP.NET 2.0 web project. Worked fine. I decided to upgrade the site to 3.5. The upgrade worked fine. I have added a IHttpHandler that required to include the following line in the web.config:<add verb=”GET,POST” path=”MyOperation.asmx” type=”MyClass”/>This line in the web.config generates the following error: “Parser Error Message: Could not load type ‘MyClass’.” This sounds like a typical spelling error in the class name. But it looks not, I checked it 1000 times. However, what i

  c# asp.net httphandler web-config ihttphandler
  Possible Duplicate:Any way to add HttpHandler programatically in .NET? Is there a way I can dynamically register an IHttpHandler in C# code, instead of having to manually add it to the system.web/httpHandlers section in the web.config.This may sound crazy, but I have good reason for doing this. I’m building a WidgetLibrary that a website owner can use just by dropping a .dll file into their bin directory, and want to support this with minimal configuration to the web.config.

  c# .net asp.net-mvc url-routing ihttphandler
  usually, when I look at a ASP.Net MVC application, the Route table gets configured at startup and is not touched ever after. I have a couple of questions on that but they are closely related to each other:Is it possible to change the route table at runtime? How would/should I avoid threading issues? Is there maybe a better way to provide a dynamic URL? I know that IDs etc. can appear in the URL but can’t see how this could be applicable in what I want to achieve. How can I avoid that, even tho

  c# .net visual-studio-2008 webclient ihttphandler
  I have a web service in which I am manipulating POST and GET methods to facilitate upload / download functionality for some files in a client/server style architecture. Basically the user is able to click a button to download a specific file, make some changes in the app, then click upload button to send it back.Problem I am having is with the download. Say the user expects 3 files 1.txt, 2.txt and 3.txt. Except 2.txt does not exist on the server.So I have code like (on server side):public class

  c# javascript silverlight ihttphandler
  I am using a handler to act as a proxy between a server with a string (actually a xml but I am trying for a string) and my Silverlight app. I have written the handler and it properly collects the string(xml). The problem I am having is converting that string from the JSON into a string that javascript can pass back to my Silverlight code. Javascript:<script src=”http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js” type=”text/javascript”></script> <script type=”text/jav

  I have a situation like the one described in this thread: How can i get the value of a session variable inside a static method in c#?However, there are no static methods here (just a class inherited from IHttpHandler) Here is my code:<%@ WebHandler Language=”C#” Class=”Telerik.Web.Examples.FileExplorer.FilterAndDownloadFiles.Handler” %>using System; using System.Data; using System.Configuration; using System.Web; using System.Text; using Telerik.Web.UI;namespace Telerik.Web.Examples.FileE
