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:

Well, thanks and sorry for my english;
