 New Comment:

I tried to figure out myself how this could be solved. I just changed
the definition of session.use_trans_sid to PHP_INI_ALL and I recompiled
my PHP module.

Now, I can change session.use_trans_sid before session_start() is
called and it works fine.

Here's the 'patch' (against PHP 4.3.2):

Why is that so? In my eyes, the point that makes sense for the rewriter
to be started, is session_start().

Furthermore: If I kind of 'deactivate' the rewriter by ini_set
('url_rewriter.tags', ''); it also has effect on links that were
already sent to output:

---------------------------------------
<?php

session_start ();

?>
<a href="a.php">Test</a>
<?php
ini_set ('url_rewriter.tags', '');
?>
<a href="a.php">Test</a>
---------------------------------------

will generate:

<a href="a.php">Test</a>
<a href="a.php">Test</a>

whereas 

---------------------------------------
<?php

session_start ();

?>
<a href="a.php">Test</a>
<?php
// ini_set ('url_rewriter.tags', '');
?>
<a href="a.php">Test</a>
---------------------------------------

appends the session id to both links.

Therefore I don't quite understand why deactivating the rewriter before
session_start() is not possible whereas modifying it is even possible
after session_start() and even after output that has to be rewritten
was already generated.

The decision to enable the rewriter is made before your script starts
running.
Once it has started it cannot be turned off again.

May I also ask why this is not possible?

------------------------------------------------------------------------

[2003-07-17 21:35:01] [EMAIL PROTECTED]

Not possible.

Description:
------------
According to http://de3.php.net/manual/de/function.ini-set.php you may
not alter session.use_trans_sid in PHP scripts, because it is only
changeable in PHP_INI_SYSTEM|PHP_INI_PERDIR.

I do not know why this is so, but in my eyes it should at least be
possible to deactivate this option at runtime.

Reproduce code:
---------------
<?php

ini_set ('session.use_trans_sid', 0);
session_start ();

?>
<a href="a.php">Test</a>


Expected result:
----------------
In an environment with 'session.use_trans_sid' activated in the php.ini
file or in a .htaccess file, it should *not* append the session id to
the link:

<a href="a.php">Test</a>

Actual result:
--------------
The session id is appended to the link and not even an error or notice
ist produced:

<a href="a.php?PHPSESSID=...">Test</a>
