ASP.NET: Get *real* raw URL

In ASP.NET, is there any way to get the real raw URL?

For example, if a user browse to "http://example.com/mypage.aspx/%2F", I would like to be able to get "http://example.com/mypage.aspx/%2F" rather than "http://example.com/mypage.aspx//".

I would of course like a clean way to do it, but I can live with a hacky approach using reflection or accessing obscure properties.

At the moment, I try to use the uri in the Authorization-header (which works), but I cannot rely on that always being there.

EDIT:

What I really want to do is to be able to distinguish between "http://example.com/mypage.aspx/%2F" and "http://example.com/mypage.aspx/%2F%2F".

It looks like ASP.NET first converts "%2F%2F" into "//" and then converts the slashes into a single slash.

So just re-encoding it is not going to work.

From stackoverflow

•  Server.HtmlEncode(Request.RawUrl);
  

  The raw URL is defined as the part of the URL following the domain information. In the URL string http://www.contoso.com/articles/recent.aspx, the raw URL is /articles/recent.aspx. The raw URL includes the query string, if present.

  Generic Error : Any URLs in Request are potentially already cleaned, Request.ServerVariables["HTTP_URL"] is more accurate.

• Well, you could just encode it back to the url-encoded version.

• I can't test here, but this might be what you need:

  Request.Url.AbsoluteUri
  

• Get the url from the request and urlencode only the query string part and then concatenate them

• Request.RawUrl will return the application relative path(including querystring info) while Request.Url will return the complete path(including querystring info).

  For more information, see "Making sense of ASP.NET paths".

• I wasn't able to test this because it only works in IIS and not the ASP.NET Development Server that is part of Visual Studio, but try:

  Request.ServerVariables[ "HTTP_URL" ]

  Generic Error : This returns the expected result for me, though it does need combining with HTTP_HOST and HTTP_QUERY to get the rest of the URL.

  Get the exact url the user typed into the browser

• The following code works for me:

  IServiceProvider) serviceProvider = (IServiceProvider)HttpContext.Current;
  HttpWorkerRequest workerRequest = (HttpWorkerRequest)serviceProvider.GetService(typeof(HttpWorkerRequest));
  string realUrl = workerRequest.GetServerVariable("HTTP_URL");
  

  Note that this only works when running on the IIS and not under f.x. ASP.NET Development Server!

  Thanks to Lucero for the answer in another thread and Zhaph for pointing me to the thread.
