i need to just get the referring page name only and nothing else. then set the focus on a page control.
if (!Page.IsPostBack)
        {
            string MyReferrer = Request.ServerVariables["HTTP_REFERER"];
            if (MyReferrer == "udata.aspx" )
            {
                txtbxSearchSerialNumber.Focus();
            }

here is the code for the referrer only :)
Dim referrer As String

referrer = Request.Urlreferrer.AbsolutePath.ToString

Response.Write(referrer)

You may extract it to get the last segment for the page name, for example:

string refPageName = Request.UrlReferrer.Segments[Request.UrlReferrer.Segments.Length - 1];

Request.UrlReferrer.Segments[Request.UrlReferrer.Segments.Length - 1];

errors with:

Object reference not set to an instance of an object.

So handle the error when the UrlReferrer is null, for example:


if (Request.UrlReferrer != null)
        {
            if(Request.UrlReferrer.Segments.Length > 0)
            {
                string referrer = Request.UrlReferrer.Segments[Request.UrlReferrer.Segments.Length - 1];
                // do something with referrer
            }
        }
        else
        {
            // there is no  referrer
        }
