Notes:

To store session related variables, create members of the TUserSession class.
Do not work with variables declared in the var section, as these are global to all threads and won't reflect session data properly.

There are several other documents that mention that global vars should NEVER EVER used in any multithreaded application, not only IntraWeb.
