Bug description: session_start() incorrectly tries to send a cookie
Description:
------------
session_start() incorrectly tries to send a cookie even when it has
already been sent. This causes problems with sessions that are closed with
session_write_close() some output has been sent and then the session is
re-opened with session_start()
The second time when session_start() is called it should avoid sending the
cookie and cache headers, since they have already been sent by the first
call to session_start(). It seems that the second time session_start()
tries to send the same cookie value as the first time, so it should be
possible to avoid sending that cookie a second time.
Reproduce code:
---------------
<?php
session_start ();
session_write_close ();
print ("Test");
session_start ();
?>
Expected result:
----------------
No output at all.
Actual result:
--------------
Test
Warning: session_start() [function.session-start]: Cannot send session
cookie - headers already sent by (output started at
