what is the use of Request.UrlReferrer? I've a 2 web pages. One page is loaded in the frame of other page. On the page load of the first page, it redirects to itself with some query strings. One the page load of second page I want to read the query string from the URL. But it shows null when I use the Request.QueryString["var1"]. Any reason for returning it null. It is the existing page that I've to modified it. I don't know why it is written this way. Help would be greatly appreciated.
