custom httphandler throwing exception while doing rewrite path

I want redirect to a file which is at the root level of the application , but i am getting the following error.

I did the following things to achieve the same

1. I have a virtual directory under root which is sample
2. Added handler with some custom name like .zpy which resolves to .net root/sample(sample is a virtual directory)

3. Added the mapping in the web.config

   <add verb="*" path="*.zpy" type="MyUrlHttpHandler, WebProj"/>
   

4. And this is the code

   string finalUrl= "http://www.test.com/test.asp";
   context.RewritePath(finalUrl);
   IHttpHandler hnd = PageParser.GetCompiledPageInstance(finalUrl, null, context);
   hnd.ProcessRequest(context);
   

I get the following error

http://www.test.com/test.asp is not a valid virtual path.

The code is getting executed but i am unable to send the request to test.asp which is at root le开发者_如何转开发vel.

i tried moving the handler to root and having handler at the root level , but its still throwing the same error

What you're doing makes no sense. Is the "http://www.test.com/test.asp" file an asp.net file? If not, then it won't be possible to get a compiled page instance!

Try using Response.Redirect or Server.Transfer instead.

Given your discussion elsewhere, if you'd actually be happy with a redirect, then that's simple:

Response.Redirect("http://www.test.com/test.asp", true);

That's going to be a lot simpler than trying to serve the original content from this request.

if you're trying to redirect to a page/handler in the root folder then simple using this path: ~/mypage.aspx.

And rather than use ReWritePath and everything else you're doing in your handler just use

Response.Redirect("~/test.asp");

This has the advantage is working in your dev environment as well as in production because you're not hard coding the complete url. ASP.NET will resolve the "~/" to be the root of your application even if the application is in a subfolder.
