first off, are you using v3.1 sr4 ?
In the code that you added to inc_top.asp
What do you have here:
' ******************************************************
' ADD HERE WHAT YOU WANT THE PREFIX OF YOUR COOKIE TO BE
' it will either be 'strCookieURL' or 'strUniqueID'
strTempCookieType = strCookieURL
' ******************************************************
the above is the default.
If you are using v3.1 sr4 then the above should be:
strTempCookieType = strUniqueID
