That makes it all really clear, thank you so much Anthony. The browser deletes the session cookie when you close it, but there's still the server session. What happens to that? I mean when you open the browser again do you get assigned another session or do you 'reconnect' to the old one maintaining the id? if yes i could use that id as my login value to identify the user and if the answer is no, then why isn't it deleted from the folder?
Sry to be a pain with this just want to make sure I really get it!! ;b
