When I use this script

### oops, don't forget to escape these! ^ ^
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");
Next, I browse around and go back one page, the cache does not expire.
Sometime I get the error messages said that the header had already start or something. So, what is the other way around to fix this problem????? Or how can I fix it????
