I cannot get request.ServerVariables("HTTP_REFERER") to work. I know it won&#039t work if the URL is typed in directly, but I can&#039t get it to work under any circumstances. In fact, when I use code to loop through and list every item in the serverVariables collection, HTTP_REFERER is not even listed, like the item doesn&#039t even exist. I am using IIS 5.0 on Windows 2000, but I don&#039t know if that has anything to do with it. Any ideas?<BR>(sorry to post this again, the last thread didn&#039t produce any results and sometimes people don&#039t read messages that already have replies!)
