Rewrite Path in Asp.Net MVC Project

// Change the current path so that the Routing handler can correctly interpret
// the request, then restore the original path so that the OutputCache module
// can correctly process the response (if caching is enabled).

string originalPath = Request.Path;
HttpContext.Current.RewritePath(Request.ApplicationPath, false);

IHttpHandler httpHandler = new MvcHttpHandler();
httpHandler.ProcessRequest(HttpContext.Current);
