How does TS know I've timed out?

Denise Bowker

I'm trying to figure out how TS (v 5.5.2 on w2k server, nt4 workstation) knows when I've timed out. The cookies are still there. The IW_AUTH cookie string, when passed into iwuser, returns a valid user definition - even DAYS after it hasn't been used.

The best I've come up with is checking that iw_auth exists and is valid then checking recent users. Unfortunately if I use my machine on my desk today and a different desk tomorrow then return to my desk I've really timed out at that machine, but my method doesn't think so.

So how the heck does TS know?
