Re^4: How to keep an object between HTTP requests?
in thread How to keep an object between HTTP requests?
Let me ask you a simple question, how is your session ID being stored on the web page?
I don't see your session ID being stored as a cookie, nor as a hidden variable anywhere. How is the web page supposed to know which session you are referring too?
Figure out how to manage your session ID on the web page and then use that ID to retrieve a specific session. Then you will be alright.
