ASP.NET 4.0 URL Routing HTTP Error 404.0 - Not Found

I have implemented URL routing in ASP.NET 4.0 using following route.

routes.MapPageRoute(
   "NewsDetails",               // Route name
   "news/{i}/{*n}",  // Route URL
   "~/newsdetails.aspx"      // Web page to handle route
    );

which gives me url like 

http://www.mysie.com/news/1/this-is-test-news

and this is working in my localhost fine.

But when I uploaded it on the server it gives ...

Server Error

404 - File or directory not found.
The resource you are looking for might have been removed, had its name changed, 
or is temporarily unavailable.

If I try http://www.mysie.com/news/1/this-is-test-news.aspx then it displays page.

Has anyone have same problem?

How can i set URL http://www.mysie.com/news/1/this-is-test-news to work on windows server 2008 ?

My solution, after trying EVERYTHING:

Bad deployment, an old PrecompiledApp.config was hanging around my deploy location, and making everything not work.

My final settings that worked:

  • IIS 7.5, Win2k8r2 x64,
  • Integrated mode application pool

  • Nothing changes in the web.config - this means no special handlers for routing. Here's my snapshot of the sections a lot of other posts reference. I'm using FluorineFX, so I do have that handler added, but I did not need any others:

    <system.web>
  <compilation debug="true" targetFramework="4.0" />
  <authentication mode="None"/>

  <pages validateRequest="false" controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"/>
  <httpRuntime requestPathInvalidCharacters=""/>

  <httpModules>
    <add name="FluorineGateway" type="FluorineFx.FluorineGateway, FluorineFx"/>
  </httpModules>
</system.web>
  <system.webServer>
    <!-- Modules for IIS 7.0 Integrated mode -->
    <modules>
      <add name="FluorineGateway" type="FluorineFx.FluorineGateway, FluorineFx" />
    </modules>

    <!-- Disable detection of IIS 6.0 / Classic mode ASP.NET configuration -->
    <validation validateIntegratedModeConfiguration="false" />
  </system.webServer>

  • Global.ashx: (only method of any note)

    void Application_Start(object sender, EventArgs e) {
    // Register routes...
    System.Web.Routing.Route echoRoute = new System.Web.Routing.Route(
          "{*message}",
        //the default value for the message
          new System.Web.Routing.RouteValueDictionary() { { "message", "" } },
        //any regular expression restrictions (i.e. @"[^\d].{4,}" means "does not start with number, at least 4 chars
          new System.Web.Routing.RouteValueDictionary() { { "message", @"[^\d].{4,}" } },
          new TestRoute.Handlers.PassthroughRouteHandler()
       );

    System.Web.Routing.RouteTable.Routes.Add(echoRoute);
}

  • PassthroughRouteHandler.cs - this achieved an automatic conversion from http://andrew.arace.info/stackoverflow to http://andrew.arace.info/#stackoverflow which would then be handled by the default.aspx:

    public class PassthroughRouteHandler : IRouteHandler {

    public IHttpHandler GetHttpHandler(RequestContext requestContext) {
        HttpContext.Current.Items["IncomingMessage"] = requestContext.RouteData.Values["message"];
        requestContext.HttpContext.Response.Redirect("#" + HttpContext.Current.Items["IncomingMessage"], true);
        return null;
    }
