Session problem

sirugo

I'm trying to implement sessions on my site for the first time.
For security reasons I have register_globals turned OFF.
What happens is that the session variable don't seem to survive from one page to another. The value of the session variable resets.
For simplicity I have reduced the code but it still won't work - running on WinNT + PHP 4.2.3, behind a firewall or two.
Instead of updating the userid-variable in the session-file it actually re-registers the variable with the new value from the second page.

First: another example (from php.net's session manual!) that actually do NOT update the variable's value. Instead it registers a new session each time I update the page:

<?php
session_start();

if (!isset($SESSION['count']))
{
$SESSION['count'] = 0;
}
else
{
$_SESSION['count']++;
}
?>

And here comes the "two-page" example:

Page 1

// Start session before all other headers!
session_start();

// displaying if it's set and it's value, before setting, shows 0 and 0
printf("isset: %d value: %d ", isset($SESSION['userid']), $SESSION['userid'] );

// setting it
$_SESSION['userid'] = 2;

// displaying again, now shows 1 and 2
printf("isset: %d value: %d ", isset($SESSION['userid']), $SESSION['userid'] );

?>
<A HREF="sess2.php">S2</A>

Page 2

// Start session before all other headers!
session_start();

// displaying if it's set and it's value, shows 0 and 0 again...should be 1 and 2
printf("isset: %d value: %d ", isset($SESSION['userid']), $SESSION['userid'] );

// setting it again
$_SESSION['userid'] = 3;

// displaying again - shows 1 and 3, but dies again when I jump back
printf("isset: %d value: %d ", isset($SESSION['userid']), $SESSION['userid'] );

Are cookies being allowed on the client web browser?

Yes, it says "Never ask" and there are a thousand already in the list.

Actually I now have tried the scripts with Opera on a Windows machine and they WORKED as they should!

Previously I tested them with my IE 5.1.6 on a Mac.
That browser DOES accept cookies. There are already many listed from recently visited sites. But still it generates a new session-file on the server each time the script is loaded.

Is there a cookie-bug with IE 5.1.6 for Mac?
Is it possible to write the session-script to work better for more machines?

Is track_vars is enabled ?

If enabled, then Environment, GET, POST, Cookie, and Server variables can be found in the global associative arrays $ENV, $GET, $POST, $COOKIE, and $_SERVER.

check that on ur php.ini file.

One more thing i Noticed was ur setting session variables
after a print() statement

Now in the version I use 4.06 It gives me an error
saying headers already written .

I think u should look into the php reference file
which is available as a download from the PHP site

I have Chm version which is pretty good

Now I cleared the list of cookies in the browser, reloaded the page and immediately found the cookie in the list.
But still - each time I reload the page that cookie gets replaced with a new one with another id.
At the same time a new session is created on the server.

But - as I said: it works flawlessly with Opera on Windows.
So the strange questions are:

Why does the session-pages work on other sites, also with my IE 5.1.6
Why does the session work on W95 with Opera (actually through Virtual PC) but not with IE 5.1.6 on a Mac.
