How to read rewritten url in asp.net 3.5

How to read the rewritten url. If I don't use .aspx in my rewritten url then 'Request.RawUrl' is not working. It is returning the original URL.

Please suggest if you have any solution to this. I am using Ionics Isapi Rewrite Filter (IIRF).

For example, if I have rewrite:

http://<mywebsite>/users.aspx?id=12&name=amitava

to

http://<mywebsite>/profile/12/amitava

Now in the same page, at some point, I want to get this rewrittern url for the purpose of pointing return url in login link. Now a login link should be:

http://<mywebsite>/login.aspx?ReturnUrl=/profile/12/amitava

or

http://<mywebsite>/login.aspx?ReturnUrl=http://<mywebsite>/profile/12/amitava

What is the proper way to achieve this? Thanks.

Solution

  • For IIRF, this is called unmangling and can be achieved by using the modifier U.

    From the IIRF manual:

    U = Store original url in server variable HTTP_X_REWRITE_URL

    Simply add the modifier U to the RewriteRule for which you would like to retain the original url. For example:

    RewriteRule ^yourexpression$ yourrewrittenurl [I,U,L]

    Then, in the code of your page, you may access the original url like this:

    Request.ServerVariables("HTTP_X_REWRITE_URL")
