hi..

the situation is like this: my clients' $_SESSION gets destroyed even after
only a few seconds of inactivity! so, with my current setting for
gc_maxlifetime (1440), it should be more than enough to have their sessions
registered for the few minutes, right? thus, i deduce that the solution may
not lie in my gc_maxlifetime value?? please correct me if I'm wrong!

thanx thanx!

You're right, the session should at least be active for the specified
gc_maxlifetime - no matter if the users click a link or not. So even if the
user clicks only once to start the session and then clicks again after 20
minutes the session should still be valid. If it's not I guess there is
something wrong on your server because the session should be alive even if
the user is not requesting any pages. Do all users have this problem and do
you have it yourself?

i do not really experience this problem.. i can click through the links
easily.. hmm.. your question sets me thinking.. do you think it has to do
with some VPN thing? my system is an intranet system and the users log on to
it through a VPN.. do you think it will cut my sessions?!

by the way, I saw this note on php.net under the gc_maxlifetime section:

Note: If you are using the default file-based session handler, your
filesystem must keep track of access times (atime). Windows FAT does not so
you will have to come up with another way to handle garbage collecting your
session if you are stuck with a FAT filesystem or any other fs where atime
tracking is not available. Since PHP 4.2.3 it has used mtime (modified date)
instead of atime. So, you won't have problems with filesystems where atime
tracking is not available.

do you think by upgrading it will solve all my problems?!

thanx a million!!

I don't have any experience with VPNs. Does it work for you if you are
logging in via VPN?

Is your server running on Windows? Have you tried using a database as your
session container?

Hi Sukanto,

I'm glad I'm not alone. :o) I'm working on an intranet, thus i can ask my
staff to enable their cookies.. but this is really not the best way.

Right now, I am trying to convert all my sessions to cookies because this is
a faster solution to solve my urgent problem. But I think as recommended by
Torsten and the others, maybe we should use the database to save our
sessions.. I do not have time to explore the PEAR packages but they look
like a good long-term solution.

By the way, do you use VPN?

Hwee
