PSEUDO!!! -random numbers

[Anon]

I'm working on a page that displays the
information in the local mySQL database
in a random order. If you refresh alot
it will eventually turn out a new order
but it isn't a new order every time. I
think it might be a refresh problem be-
cause i have tried the mc_rand function
and it doesn't work either.And there is
a no cache tag in the header.Maybe it's
Cacheing on the server but i dont know!
Please help! - Remo

are you using php's mt_rand() function? are you making sure to seed the engine if it is php? then try adding these:

header("Cache-Control: no-cache, must-revalidate");
header("Expires: Wed, 20 Jun 2001 12:11:20 GMT");

and also:

header("Pragma: no-cache");

If this doesn't work (IE will sometimes ignore these headers), to refresh the page you can link to it and append some random stuff to the query string. IE gets the page if the query string is different. It ain't pretty but it gets it refreshed. I use:
<a href="page.php3?refresh=<?=substr(md5(microtime()),0,4)?>">refresh</a>
