Status: Feedback
Bug Type: Session related
Operating System: Debian
PHP Version: 4.1.1
Assigned To: yohgaki
New Comment:
I've tried a number of different combinations of both php.ini settings
(zlib.output_compression and session.auto_start) as well as in-line
function calls (session_start, ob_start("ob_gzhandler")), and in every
situation I've found, the transient SID is lost when compression is
turned on.
Note that I'm using PHP 4.1.1 (4.1.2 is compiling as I type this) on
RedHat Linux 7.2, and did compile it with --enable-trans-sid.
Here's a summary of the 5 different tests I tried:
[Test 1]
php.ini:
zlib.output_compression = Off
session.auto_start = 0
--snip--
<?
session_start();
session_register("testvar");
$testvar = "test value";
?>
<a href="/test.php">Testing</a>
--snip--
Result: PHPSESSID gets appended correctly.
[Test 2]
php.ini:
zlib.output_compression = Off
session.auto_start = 1
--snip--
<?
session_register("testvar");
$testvar = "test value";
?>
<a href="/test.php">Testing</a>
--snip--
Result: PHPSESSID gets appended correctly.
[Test 3]
php.ini:
zlib.output_compression = Off
session.auto_start = 0
--snip--
<?
ob_start("ob_gzhandler");
session_start();
session_register("testvar");
$testvar = "test value";
?>
<a href="/test.php">Testing</a>
--snip--
Result: PHPSESSID is lost and not appended.
[Test 4]
php.ini:
zlib.output_compression = On
session.auto_start = 0
--snip--
<?
session_start();
session_register("testvar");
$testvar = "test value";
?>
<a href="/test.php">Testing</a>
--snip--
Result: PHPSESSID is lost and not appended.
[Test 5]
php.ini:
zlib.output_compression = On
session.auto_start = 1
--snip--
<?
session_register("testvar");
$testvar = "test value";
?>
<a href="/test.php">Testing</a>
--snip--
Result: PHPSESSID is lost and not appended.

Could you try to start session manually in script and report the
result?
Does it work now? I think it should.

User should make sure *not* to use session auto start to make trans sid
work when zlib.ouput compression is enabled.

Note to this report.
The reason trans sid does not work is related to output handler
registration order. This is not a simple fix at all. (I might set
status to Suspended)
User should make sure *not* to use session auto start to make trans sid
when zlib.ouput compression is enabled.
The reason SID is not defined is not related to output control.
I also made a patch to define SID constant always, but it's not applied
to CVS. (yet)
If you have problem with SID not defined *even if* you have used
--enable-trans-sid when you configure PHP and session.trans_sid = 1 in
your php.ini, please submit a new bug report as session problem.

When I compress my output with ob_gzhandler or with
zlib.output_compression trans sid doesn't work.
Without output compression trans sid works fine.
I use PHP 4.1.1 (Debian Package)
In following code php doesn't add the sid to the testlink
(sessioncookies are off)
<?php
session_start();
session_register("dummy");
$dummy=1;
if (!$sid) {
header("Location: $PHP_SELF?".SID);
exit();
}
?>
<a href="test.php">Testlink</a>
