ok....

still have questions regarding how to handle a user/session of a user who
kills their browser. in this case, the user's session information would
still be in the db for the session handler...

am i correct in understanding/assuming that i could iterate through the list
of sessions in the session handler, and the session information for users
who aren't on the site, will essentially be invalid???

also, i'm trying to get my hands around the garbage collection function, as
it relates to users who aren't on the system any more...

information that i've seen in the articles haven't given me insight for this
isssue... if i can see how to deal with this situation, then i can craft a
way for an admin to more or less be able to generate a list of users/people
who are actually on the system/site.

as an exercise, i took a look at mambo (the cms) and realized that it
doesn't handle users who simply shut down their browser while on the
system...

thoughts/comments...
