+Status: Bogus
Bug Type: Session related
Operating System: Debian GNU/Linux
PHP Version: 4.4.4
New Comment:
This is called "deadlock" and you did it yourself.
Session file is locked, so every apache request will wait for the
previous one to finish before using it.
You're sending a request using the same session ID, while the session
file is locked, so we got the following situation:
- a.php has locked session and is still executing, waiting for file().
- but file() will never end, because b.php is waiting for session to be
unlocked and that won't happen until a.php is finished executing.

--enable-trans-sid
session.auto_start Off
session.bug_compat_42 On
session.name PHPSESSID

---------------
script a.php
---
<?php
session_start();
$_SESSION["foo"] = "bar";
echo session_name() ."<br />";
echo session_id() ."<br />";
echo $_SESSION["foo"] ."<br />";
echo implode("", file("http://"; . $_SERVER["HTTP_HOST"] . "/b.php?" .
session_name() . "=" . session_id()));
?>
---
script b.php
---
<?php
session_start();
echo session_name() ."<br />";
echo session_id() ."<br />";
echo $_SESSION["foo"] ."<br />";
?>
