>Using 'cookieless=true' doesn't prevent you from using cookies - just means that the sessionId is in the URL not in a cookie. So if, for example, you wanted to store the user name per session you could use a cookie with the SessionId as the key and 'UserName' as a sub-key. Something like this.

So, we are talking about the ASP.NET session and not the Member.Session field I am using. Does this mean you see visually in each URL request a longer URL with the ASP.NET session?
