Those browsers should be fine, but forcing a reload (the control/shift + refresh) is always worth trying. Maybe I should compile php myself disabling things i dont need and see it > will make any difference. > You can see what's in your PHP build by creating a script that just contains the following.. <?php phpinfo(); ?> Run that and check the output. If you got the binary from php.net then chances are that you don't have any opcode caching modules in there. It's also worth doing a variation on Micky's suggestion - when I want to make sure a script has actually been executed rather than cached data being served I put a call to echo date('r'); in an appropriate place. That way the script output will display the current date and time which should change with each request. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/
