>that indeed works but i have the problem that create a session variable to carry information back to the original page.

Try parsing the string.

>AdminSiteBran.asp?success=111#tag

i.e.: vbscript's InStr()

q_success = Request.QueryString("success")
q_success = Left(q_success,InStr(Trim(q_success),"#"))

Session("success")= 1 'Whatever your flag is.

Hope this helped.
