Aren't session variable preserved using "Header('Locati on: xxx')"?

I am trying to pass some info to another page on my site. I set
"session_start( )" in page 1, assign a session variable to a value, then
execute a "header('Locati on: ....')." But on the target page I don't get
any session variable values! BTW, I used a relative location in the
Location header, not an absolute URL. The behavior looks like it started
another session, but it should not have.

Ideas?

TIA,

Larry Woods

Before the header("locatio n: "), call session_write_c lose().

That gave me some serious headaches with mac-based browsers hanging.
Terrible stuff :)

Oh, and you should always use absolute URLs with location. Relative ones do
work, but that's not guaranteed. You could make a function like this to
take care of that for you:

function bounce($url) {
if (sustr($url, 0, 1)=="/") $url="http://".$_SERVER["HTTP_HOST"].$url;
session_write_c lose();
header("Locatio n: ".$url);
exit();
}

or just use that one :-P

Thanks, but I still can't get it to work. Check the following:

Originating Page:

<?
if($_POST['repost']=='y') {
session_start() ;
$_SESSION['xxx']='test';
session_write_c lose();
header('Locatio n: http://www.mysite.com/test/testsess2.php') ;
exit();
}
?>

Nope, you need it in every page.

Also, I mistyped - it's session_start() .
