Hello guys; i'm having a problem with session behavior; i'm going straight to
it, but first some considerations:
PHP Version 5.2.5IIF 5.1Running on localhost (XP machine)I start sessions at the top of every page.
A the start of a test page, just as example, i do the assignment: $_SESSION["username"]
= "aaa";
At the end of the same page i print it's value: echo $_SESSION["username"];
And i get the layout: "aaa", as expecteed.
Then I redirect to another page. On that one, after initializating the session
("session_start();") print again the $_SESSION["username"] content and the
result is empty. If i try the same code on a server (all this is on my local machine), the code
works as expected; so i think it is a configuration problem, here is my php.ini part that
correspond to session configuration, so you can tell my if i'm doing anything wrong, long comments

It works for me; I am using php-5.2.5 with lighttpd and FastCGI.
I called session_start() on both the pages.
and
I have enabled session.use_trans_sid.
You can temporarily override it from the php script by using this -
<?
//...other code
ini_set("session.use_trans_sid",1);
//...other code
?>
Try and report again.
