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

You can see what's in your PHP build by creating a script that just contains
<?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.
