If you use zlib's output compression, php doesn't autoappend the SID anymore (used session.auto_start)

Testet on:

- Win2k
 - Apache 2.0.39(apache.org binary)
 - PHP 4.2.2(php.net binary)
 - php.ini

and
- Debian 3
 - Apache 1.3.26
 - PHP 4.2.2
 - .htaccess

Changed Status to OPEN.

I've tried the latest from snaps.php.net/win32 downloaded today.
PHP-4.3.0-dev
PHP API 20020918 
PHP Extension 20020429 
Zend Extension 20021010

If i use zlib.output_comression = On, browsers are showing me just binary data.
But there has come a new directive and i don't know what to set there -> zlib.output_handler = ?

Don't use it if your browser doesn't support it.
 [2002-11-11 10:19 UTC] m dot wallner at iworks dot at 
What do you mean, "if my browser doesn't support it"?

Mozilla and IE did support it.

"output_handler = ob_gzhandler" works fine with these browsers.
"zlib.output_compression = On" worked fine with these browsers with PHP 4.2, except trans_sid didn't work.

And now zlib's output-compression is not working anymore.

Why is that Bogus?

You should have mentioned that in the first place..
(that it worked before)

Are you by any chance trying to use both methods at the same time ?

Sorry, my english is not that good.

> Are you by any chance trying to use

I'm not using

output_handler = "ob_gzhandler"

and

zlib.output_compression = On

at the same time, if you ment this.

"ob_gzhandler" still works fine, even with session.use_trans_sid = 1, but zlib.output_compression always serves trash in this version.

So it might be some bug then.
 [2002-12-29 06:38 UTC] m dot DOT dot wallner at iworks dot DOT dot at 
So here is my conclusion:

I've just tried PHP 4.3.0 Final today.

zlib's compression works fine now, and
session.use_trans_sid won't work if and
ONLY IF you use session.auto_start.

trans_sid works fine if you start the 
session manually by calling session_start().

Don't know if this Bug should be closed?

Bye,
Michael

If I try to use trans_sid with php 4.3.0 final it doenst work. ZLib output compression is off. The test I use is as following:

ini_set('session.use_cookies','0');
ini_set('session.use_trans_sid','1');

session_start();
print '<a href=bug.php>Bug</a>';

There is no session id appended to that link. 4.2.3 worked fine. Most settings are the same as in the php.ini.recommended  comming with 4.3.0 final.
 [2003-01-07 10:27 UTC] m dot DOT dot wallner at iworks dot DOT dot at 
You AFAIK can't set session.use_trans_sid with ini_set, because this param is only writeable by PHP_INI_SYSTEM or PHP_INI_PERDIR directive -> you can read this at http://www.php.net/manual/en/function.ini-set.php

Bye,

Please try using this CVS snapshot:

  http://snaps.php.net/php4-STABLE-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-STABLE-latest.zip

This might have changed a bit, see bug #24315 (seems like same issue?)
