ASP.NET: Find out where a visitor came from
From Wiki
Summary: Find out where a visitor came from
If you want to track which page or site a user has come from, you can use the referrer information. This is located in the Request.UrlReferrer object e.g.
- Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
- Response.Write(Request.UrlReferrer.ToString())
- End Sub
Caution: you may find that this is not 100% reliable as users can tell their browser not to send the referrer or they can even alter it so only use this if you are aware of this.
