I've been scratching my head over this for sometime now.
I'm sure I'm doing something wrong and hope someone can help. The problem is simple: 
<?php
session_start();

if (isset($HTTP_SESSION_VARS['count']))
{
   $HTTP_SESSION_VARS['count']++;
}
else
{
	print "NOT registered:";
        $HTTP_SESSION_VARS['count']=0;
}


?>

Hello visitor, you have seen this page <?php echo $HTTP_SESSION_VARS['count'] ?> times.<p>


To continue, <A HREF="http://localhost/jobs4us/main.php?<?php echo SID?>">click here</A>



-- The above code is available on the  php site.
Problem:every time I reload the above page, or link to it from another page, $HTTP_SESSION_VARS['count'] always shows 0. Why? I can see the session is saved in my temp file (size 1K), but when i reload the page, why does the code 'think' that the session is not registered? Of course, I tried session_is registered("count") but to no avail. Any help would be appreciated.

oops - left out session_register("count"); so the code looks like this:
<?php
session_start();

if (isset($HTTP_SESSION_VARS['count'])) {
   $HTTP_SESSION_VARS['count']++;
}
else {
	print "NOT registered session:";
	 session_register("count");
   	$HTTP_SESSION_VARS['count']=0;
}


?>

From http://www.php.net/manual/en/function.session-register.php:

"For each name, session_register() registers the global variable with that name in the current session."

and further

"If you are using $HTTP_SESSION_VARS/$_SESSION, do not use session_register(), session_is_registered() and session_unregister()."
