ASP.NET MVC 2.0 + Implementation of a IRouteHandler does not fire
- by Peter
Can anybody please help me with this as I have no idea why
public IHttpHandler GetHttpHandler(RequestContext requestContext)
is not executing. In my Global.asax.cs I have
public class MvcApplication : System.Web.HttpApplication
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
routes.Add("ImageRoutes", new Route("Images/{filename}", new CustomRouteHandler()));
}
protected void Application_Start()
{
RegisterRoutes(RouteTable.Routes);
}
}
//CustomRouteHandler implementation is below
public class CustomRouteHandler : IRouteHandler
{
public IHttpHandler GetHttpHandler(RequestContext requestContext)
{
// IF I SET A BREAK POINT HERE IT DOES NOT HIT FOR SOME REASON.
string filename = requestContext.RouteData.Values["filename"] as string;
if (string.IsNullOrEmpty(filename))
{
// return a 404 HttpHandler here
}
else
{
requestContext.HttpContext.Response.Clear();
requestContext.HttpContext.Response.ContentType = GetContentType(requestContext.HttpContext.Request.Url.ToString());
// find physical path to image here.
string filepath = requestContext.HttpContext.Server.MapPath("~/logo.jpg");
requestContext.HttpContext.Response.WriteFile(filepath);
requestContext.HttpContext.Response.End();
}
return null;
}
}
Can any body tell me what I'm missing here. Simply
public IHttpHandler GetHttpHandler(RequestContext requestContext) does not fire.
I havn't change anything in the web.config either. What I'm missing here? Please help.
