Sorry....sessions ... again...with code...

|Hello all, I'm mad with me....sorry but see if can understand why I'm mad. Copy the 3 attached files, and run it. In one.php just click to the link (it works.....), now in two.php you can see: " and now: aaaaaaa", cool hum... Clicking in OFF link you can see the result of phpinfo, but section of Apache Evironment, in HTTP_COOKIE you (at least I have) the PHPSESSID with value, in spite of in off.php code I make a session_destroy???? Now if you use history back button, go to two.php, and OK the session variable dont appear, Back again, Forward and voila' here is aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa. I have try to follow some Jeff Armstrong tips, but I have no success.Thank you very much Jeff (really...I'm no jocking...). Any ideas ??
