Here's an ASP page that will give you details of the ASP server variables, cookies etc. on your server. Live example can be found here.
Code ASP:
<%
Sub aspinfo()
Dim strVariable, strASPVersion
Dim strCookie, strKey, strSession
 
'Retrieve the version of ASP
strASPVersion = ScriptEngine & " Version " & _
ScriptEngineMajorVersion & "." & _
ScriptEngineMinorVersion
