Logging in from outside VB
 

I have an application I'm trying to integrate with VB.

When I login (outside VB) I also want to be logged in to VB.

Now, my application uses $_SESSION to store userID, email, username and stuff like that. I want that data to also be available to VB.

How can I do this easily?

I also need the reverse, logging in from VB and automatically being logged in into my custom application, with access to $_SESSION.

Thanks for any helps or hints, vB is slowly driving me insane, the code is a big mess :p

Also, if a user remains outside the forum for the first half hour, would that mean the session for the forum would have timed out? I don't want to be doing those update lastactivity db queries on each page outside my forum.. why doesn't VB use normal $_SESSIONs?? :( or do I just need to update the bblastactivity cookie?
