[RESOLVED] Strange cacheing and sessions?

Yari

Hi,

I am building a automated image gallery + CMS for a client, but keep having the weirdest caching problems.

I have figured out that when I use my sessions file, the cacheing goes all screwy, not remembering what page its on, or showing past pages instead of the new ones. Only repeated refreshes convinces my browsers (Firefox 1.5 & Safari 2) that this is actually a different page!

PHP Version 4.4.2

Have tried all kinds of ways to stop the cacheing, such as:

// No cache
	Header('Cache-Control: no-cache');
	Header('Pragma: no-cache');

And other meta tags to stop the cacheing... with no luck.

The only thing that seems to ease (but not stop completely) this weirdness is disabling my sessions file. Which I obviously need for certain things!

Sessions.inc.php

<?php
	session_start();

session_register("album"); // Album id
session_register("Gallery"); // Gallery id
session_register("meta_view"); // Meta View (Theme / Mood / Keywords)

session_register("advanced"); // Advanced Options
?>

Anyone got ideas on this?

Cheers,

Yari

well, right away...is your server frontended by a caching proxy?

The only addition sessions add to the equation is that your browser sends an additonal header:

Cookie: PHPSESSID=7adfg54s787g43512405e2532345a08f13

But that header is constant. Has to be or sessions wouldn't work.

Ok, thanks.

I will check with my host about the caching proxy... but the sessions thing doesn't make any sense to me either.

Thanks, will let you know once I hear from my host.

bye

My host does not use proxy cacheing... and the problem is definitley related to my sessions file.

I attempted taking out different vars from the session file, but unless I stopped the session start altogether it didn't affect the cacheing problem...

My session file is:

<?php
	session_start();

session_register("admin_visit");
?>

And still no idea!

The host I use also has other websites, none of which have any problems...

Thanks,

yari
