delegates asp.net-web-api httphandler
I have an ASP.NET Web API project and on initial user login, the username and password are sent in an http header over SSL and validated by the server. The server creates a database record with the UserId, a randmon 64 character string (UserToken), expiration date and the client IP address. The UserToken is then sent back to the client and then be stored in a cookie.All subsequent requests send the UserToken in an http header and that is validated using the calling IP address by the server.This

asp.net asp.net-mvc iis iis-7 httphandler
I have an mvc app developed and tested with Cassini. Deployed to my site on GoDaddy, and the default page comes up fine. Click to log in, and I get a 404.I’m running under IIS 7 there, so this is unexpected. My routes are pretty plain:routes.IgnoreRoute(“{resource}.axd/{*pathInfo}”);routes.MapRoute(“Default”, “{controller}/{action}/{id}”, new { controller = “Public”, action = “Index”, id = “” } );routes.MapRoute(“Report1”,”Re

c# asp.net http iis-7 httphandler
We have an HttpHandler that deals directly with binary posts over HTTP from custom client software. The client software occasionally sends data which results in IIS 7 responding with a 400 – Bad Request. Since the “400 Bad Request” is special in that HTTP.SYS transparently handles it in kernel mode without notifying user mode of anything, no errors are raised to be handled in ASP.NET. Is it possible to catch this http 400 in ASP.NET, so that I can write specific data to the Response stream in th

c# debugging iis httphandler
I am using IIS 6 on 2003. I have created a HTTP handler dll that inherits from IHttpAsyncHandler. The dll builds into the inetpub\www8080root\common\bin directory. It is meant to intercept all requests.The web site is set to monitor port 8080. I have created a common folder in the www8080root directory and have created a virtual directory in II6 to point to it. I created a web.config file in the common directory<?xml version=”1.0″ encoding=”utf-8″?> <configuration> <system.web>

asp.net-ajax telerik httphandler scriptmanager webresource.axd
We have a web application with 2 web.config files. I’m using the telerik:RadScriptManager control within an ASP.NET page. There is web resource file (WebResource.axd) that this control needs access to for it’s ScriptReferences. I think this .axd file contains the JavaScript files for Telerik’s controls. All of our Rad Controls are implemented in a separate web application (.csproj) project called “admin”. The root web application project (.csproj) has a folder called “admin” where all of th

iis7 crystal-reports reportviewer httphandler
I have a reportviewer control that works fine locally and on a iis 6.0 box, but when deployed to the IIS 7 webserver, the control has broken images. The report does return data but the top bar has broken images and buttons. Using Fiddler I see that the images requests are returning a 404 or 500 error. I got the 500 after changing some HTTP handler stuff. There is a lot of stuff on the web about this error and I have tried them all but w/ no luck. Things I have checkedInstalled reportViewer

c# asp.net asp.net-mvc-4 httphandler iis8
There are lots of questions answering this, but none of the answers are working for me.Originally, I was getting a 405 when I was trying to PUT or DELETE (probably other verbs too). Looking at some questions, the solution seemed to be to change the Handler Mappings.I changed the following:ExtensionlessUrlHandler-ISAPI-4.0_32bit ExtensionlessUrlHandler-ISAPI-4.0_64bit WebDAVI noticed that the verbs were already in the One of the following verbs box, so in desperation I changed it to accept all

c# asp.net .net iis7 httphandler
I’m having trouble getting IIS 7 to load this handler I’ve written. I’m keeping things really simple to start with. I have a Handler.cs file with the following code in it: public class Handler :IHttpHandler {public bool IsReusable{get { return false; }}public void ProcessRequest(HttpContext context){context.Response.Write(“asdfasdf”); } }I have put this file in the root directory.I want to execute this code whenever the root directory receives a request, so I have built the handler file like thi

c# asp.net http-headers httphandler http-compression
I have a custom HttpHandler in which I manually enable output compression, like so:context.Response.AppendHeader(“Content-encoding”, “gzip”); context.Response.Filter = new GZipStream(context.Response.Filter, CompressionMode.Compress);This works nicely for most requests, but when an exception is encountered the “Content-encoding” header disappears from the response, while the compression filter remains in place. The result is that the error page is gzip compressed, but the browser receives no hea

c# asp.net httphandler httpmodule
Currently when trying to submit transaction that contain dropdown that has text containg angular bracket as e.g. “<abcd>”, I’m getting 500 internal server error since ValidateRequest=true by default and throws unhandled exception before it reached to page handler since its Cross site scripting problem. Is there a way to intercept and modify request object in HttpModule or Glabal.asax since I know Request object is readonly.I’ve been breaking head for almost three days but not able to get a

iis7 httphandler integrated-pipeline-mode wildcard-mapping
Helo community,I migrate my application to the IIS integrated mode. (IIS 7.5)I’m using the IIS wildcard mapping, so every request is processing through my application.In the classic mode I get for each unhandled request a System.Web.DefaultHttpHandler, but in integrated mode there both (HttpContext.Current.CurrentHandler / HttpContext.Current.Handler) null.Can I set a default handler for all unhandled requests?Thanks and best regards!

I’m trying to hack into an external HttpHandler to return a FileStreamResult in my MVC application. I want to be able to have a clickable link and I’d rather not use JavaScript.The path is correct, I can call the path directly in the browser; I just get the following error:The request was aborted: The connection was closed unexpectedly.I can call the path directly in the browser.My code so far:public FileStreamResult Test(){Uri uri = this.ControllerContext.HttpContext.Request.Url;string leftPart

I have created an ashx handler that returns an image to my flex app. If I go directly to the url for example (www.mysite.com/handler.ashx?id=34) the browser will display the image. If you set the source of an image control in flex to the same address. I get “Error #2124: Loaded file is an unknown type.”. Any hints
