I have some password protected pages that redirect the user to a login page if they are not signed in. What I need to know is the exact URL the user originally clicked on before being redirected. For example, if I have a link like this:<BR><BR><a href="http://www.cnn.com/index.asp">CNN</a> on page http://www.abc.com, then HTTP_REFERER will return "http://www.abc.com". PATH_INFO will return "/index.asp". What server variable or method can I use to return "http://www.cnn.com/index.asp" after the user is redirected using Response.Redirect ?
