 [2002-11-20 15:52 UTC] thibaud at phpnet dot org 
I have just compiled PHP in CGI because it improves sharply the performances of my machine (load fall).
On the other hand, I have a big probleme with the sessions. 

INDEED, when one makes a simple script :

By going on the script with IE: The session is created well on the server but it is empty. (File of session empties).

WHILE by going there with Netscape, it work. 

The script handled by php in module works perfectly under both navigators. 

I have heard about such a probleme but I did not find solution which works. More inquietant still (!) : 
I compiled as on 3 different servers and on two, it does not work while on the other whom has EXACTLY the same config php + apache + configure lines, it works!!! 
(http://80.245.32.147/phpinfo)

You can consult the phpinfo of server who does not work on http://phph2.phpnet.org/phpinfo.php 

A simple script of session :
http://www.phpnet.org/script.php work perfectly
http://phph2.phpnet.org/script.php doesn't save the session !

Have you met the probleme? 

Please help me !

PS: I tried all the versions:) php 4.2.2 , 4.1.2 , 4.2.3.... And nobody works.

Please take a look at the solution on this bug report:

  http://bugs.php.net/bug.php?id=20025

As this only happens with IE, I think it might be 
the same problem..
 [2002-11-22 12:16 UTC] thibaud at phpnet dot org 
Yes but no :)

It is the same problem with this config.

I desespere !
Please help me.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Your example session code is not correct. It should be something like this:
<?php
session_start();
$_SESSION['essai'] = "test";
header("Location: script2.php?".session_name()."=".session_id());
?>

<?php
session_start();
echo $_SESSION['essai'];
?>
 [2002-11-23 16:41 UTC] thibaud at phpnet dot org 
No !

Because the register_global is defined as On.

register_argc_argv
 On On 
register_globals
 On On 

And when the register_globals is defined as On, the session params can be used as variable ...

It's indeed a bug because the variables of session are not sauved in files. (0 lines in the file created).

In every case, I decided to go back php in module apache because mod_bandwidth of apache seems to talk an incompatibility with php in CGI (the scripts php are not  interpretes when it is activated..) 

If you have a solution for the two problems...

To part it, please , think you whom it is preferable to cross php in CGI or to leave it in module (by knowing that I have a lot of traffic (90 requests per second))

Please HELP ME !
I'm very blocked by that problem.

Thanks a lot for you reply

Does it work when you try my suggestion of using $_SESSION ?
 [2002-12-07 02:43 UTC] thibaud at phpnet dot org 
I have solved my problem !

In the apache configuration :
KeepAlive Off

http://www2.phpnet.org/phpinfo.php

Its always a php bug !

Thanks but your suggestion of using $_SESSION did not resolv the problem.
My solution work fine...

Cordially
 [2002-12-07 10:07 UTC] iliaa@php.net 
Do you have any ideas as to why turning KeepAlive off solved the problem?
 [2002-12-07 10:12 UTC] thibaud at phpnet dot org 
NO :)
I don't know why but Its working fine when KeepAlive is in Off and doesn't work when it is defined as On !

If you have an idea...
It is php-4.1.2, php-4.2.2 or php 4.2.3 and apache 1.3.27
(other versions < 4.1.2 is exactly pareil....)
