Here is the code that calls the UseSession function,
and it passes the sid that was from the GetSid function
through the javascript.
xmlhttp=new XMLHttpRequest();
if(xmlhttp2) {
url = "mail.py/GetMailboxes?sid=" + sid;
xmlhttp2.open("GET", url, true);
}
I have a sneaking suspicion that each req is
overriding my sess = Session(req, sid) with a new session id
and it may be because the XMLHttpRequest doesn't pass
the cookie that is generated for the session to the page,
and insteach with each calls it thinks a new session should
be created.
I'm working on trying to figure more out...
