Regarding JHoagland's thread about the sessionID being part of the URL, I think this is an highly unusual practice. I doubt any shopping cart application would use this, except for putting the session ID with a hash of it in a cookie and matched the cookie to it. For instance, if you look at the URL for this message in Internet Explorer, you should only see the ForumID and the MessageID. The session information is kept in a cookie, stored locally on your PC. Regarding the expiration time that Khai is mentioning. The default expiration date of a cookie is the current session. If the web master doesn't set the expiration date, your cookies will expire upon exiting the browser window. Cookies can be set to never expire also. Anyhow the discussion of cookies is quite long-winded, and often repeated. Most are innocuous, except tracking cookies (Ad Aware will delete many of these). There are many resources discussing them, see attached link for one.
