Question

How do I get the referrer URL in an ASP.NET MVC action? I am trying to redirect back to the page before you called an action.

Answer 1

Request.ServerVariables["http_referer"]

Should do,

Answer 2

You can use Request.UrlReferrer to get the referring URL as well if you don't like accessing the Request.ServerVariables dictionary directly.

Answer 3

Bear in mind that not all user-agents (AKA browsers) will send the referrer information, and some may even fake it.
