I have never in my time as a professional webdeveloper (4 years) experienced that a session "forgets" anything and I have used it ALOT, so my guess is that this session of yours doesn't get set at all. If you post yur real code instead of pseudo-code it might be easier to debug...

...and for the record Bunce, sessions don't get sent to the browser. Sessions are stored on the server (and cookies are stored on the client) and once you reference either one of them in your ASP they are set right away.
