Intermittent problem with Session Variable and IE6

[Anthony]

I have a php app that is in the final stages of testing and has been
tested by over 30 separate users.

One of the testers is having an intermittent problem which seems to be
caused by a session variable not being read properly in about 1 in 3
requests even though the variable is getting set correctly in the
session temp file. It only happens after a form has been submitted
(using POST or GET doesn't seem to make a difference).

This bug only occurs when using IE6 (XP SP2) on this particular
machine, it does not occur when using Netscape7.1 on the same machine.

It occurs when testing against the main server Linux/Apache
1.3.29/PHP4.2.3 and against my dev machine Win2k/Apache 2/PHP4.3.4

None of the other testers seemed to experience the same problem.
Has anybody seen anything similar or know of any possible causes?

Anthony,

I have been seeing the exact same problem! This is the reason for me
joining this newsgroup. Sometimes with IE6, when users log into my app,
the session does not set. My screen merely flashes and goes back to the
login screen. Then other times it works just fine. My default browser
is Mozilla's FireFox and I have never had this trouble (NS7 did not give
a problem either). I have checked the Privacy settings, fiddled with
them but with no luck. My production/test machines are Linux/Apache
1.3.27/PHP 4.3.1. Any help would be greatly appreciated.
