problem with sessions config.

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 where removed:

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.

Thanks for your answers people; but i'm still having the problem, ¿any approach to the reason?. Remember everything works fine in on-line servers, so it may not be a problem of the code, but a config. one;cheers,
Nicolas.
