How to get the previous page's url address under ASP.NET C# code?

 

[Ray Costanzo [MVP]]

Try

Request.ServerVariables["HTTP_REFERER"];

Note this will not be populated 100% of the time. It's up to the browser to
send this information to the server. And even if it does under normal
circumstances, some paranoia firewall software prevents this data from going
in http requests. More details on the non-reliability here:
