How to get previous page URL in C #

Question

How to get previous page URL from C # IE ..

Request.UrlReferrer" not working in IE

Please, help...

Answer 1

Try Request.ServerVariables["HTTP_REFERER"]

But Request.UrlReferrer also gets its data, so if there is no value in this variable, there is no way to get it.

And it should work fine in IE ..

Answer 2

Browsers do not always send a referrer, so you cannot rely on access to this information.

See the answer for Does http-equiv = "update" save referrer information and metadata?
