Description:
------------
Using the PHP sessions, I found a strange behaviour when I accept the session cookie manually (my browser setting: ask for cookies). On some servers, every page containing sesssion_start() tries to set this cookie again and again, with identical name and value. Unfortunately the Internet Explorer accepts this only twice, then it hangs. Mozilla/Netscape/Opera accept cookies without crashing.

This problem refers even to large sites. I can give you examples by mail.

I saw this problem also on apache 2.0.40/PHP 4.2.2 and apache 1.3.26/4.3.0, so there might be other dependencies (OS? Apache?), which I can't reproduce.

My build for apache 1.3.29 / PHP 4.3.6:

'./configure' '--with-mysql=/usr' '--with-apache=../apache_1.3.29' '--enable-track-vars' '--enable-trans-sid' '--with-gd' '--with-jpeg-dir=/usr/lib' '--with-png-dir=/usr/lib' '--with-tiff-dir=/usr/lib' '--with-freetype-dir=/usr/lib' '--with-zlib' '--enable-bcmath' '--with-ftp' '--enable-ftp' '--with-mcrypt' '--with-mhash' '--with-gettext' '--with-config-file-path=/etc'

php.ini with no changes.

There are no error messages in any logfiles (php/apache).

Similar to Bug #26502, but it seems not to be a browser problem as sniper says.


Reproduce code:
---------------
<?
  session_start();
  $var = "any value";
  session_register("var");
  print_r( $HTTP_SESSION_VARS );
?>

Note: The browser setting must be "ask for cookies" to reproduce the behavior.

Expected result:
----------------
At the first page visit, my browser asks me to set the session cookie. I accept. Reloading this page should not try to set the cookie again.

Actual result:
--------------
The cookie is set every page view.
