Difficult to help you because there are many method of session :
- where do you store the sessions_variables : in local file, db or cookie ?
- how you transmit the session id, beetween pages(runtimes) : cookie, $GET
link, database ?
Did you check the availability of user cookie if you use it ?
Because if in each page of your application you define a session variable
it's sure it will be every time here.
But the problem of session it's to transmit its ID between different pages,
or session will be reset.
If a user don't authorised cookie you must transmit the session id by db
storage or $Get link.
Also I don't see, a php modification during the last upgrades to explain
that's kind of session problem.

Hi !
I have a very weird issue since the last Apache upgrade (-> 2.2.8-r3, a
month ago), but I'm not sure it is related (well, I'm pretty sure it's
not).
Like many people, I've written an application that use PHP session
variables, like $_SESSION["my_variable"].
Sometimes (it doesn't happen all the time), _some_ of these variables are
not written in the session file and they are lost after a simple
header("Location:...); (same domain). The session file is in the right
directory (permissions are fine), but some of my variables are missing.
The facts :
- Apache 2.2.9 + PHP 5.2.6_rc4 running on a Gentoo (up-to-date)
- all my scripts begin with session_start(). I've tried to add
session_write_close() before every header(Location:...) call, it doesn't
help.
- I didn't change anything in my program (it has been running just fine
for 2 years), it just began to fail from time to time (I would say 10
times a day). There is no hidden unset() function : it would fail for
everyone.
- these variables are all set correctly, and they don't have reserved
names.
- only a few variables disappear, but they are always the same ones (could
it depend on their position in the session file ?!?)
- the session files are very small (max 100ko)
- it seems that it doesn't depend on the browser, but IE6 and IE7 seem to
be the most affected ones (it may be because my users mostly use these
browsers).
- I can't reproduce this issue from my local network (any OS/browser - it
would be too easy :)
- reverting to the previous stable Apache and/or PHP versions doesn't
help.
- I didn't change any php.ini directive.
Any idea ?
Thanks !
PS: if you need more details, just ask. The only thing I can't do is
pasting the code : the scripts are quite huge.
