Php Header Vs Htaccess Header

[yaashul]

I have set the following thing in .htaccess

<FilesMatch "\.(html|htm|cgi|pl|php)$">
Header set Cache-Control "max-age=0, private, no-store, no-cache, must-revalidate"
</FilesMatch>

It tell that no php script shud be cached by browser or other user-agent.

But if I want only 1 php script to use other setting I can use

header('Cache-Control: public');

function in that script. But the problem is php is not able to change the header setting done in .htaccess?

<?php
header('Cache-Control: public');
?>

showing the following header

Cache-Control:max-age=0, private, no-store, no-cache, must-revalidate

while it shud show

Cache-Control: public

Any specific reasons?

Headers are already set, you can only reset the headers if you redirect, but then it will hit the .htaccess again on the next request.

Personally I'd use a conditional directly in the .htaccess to ignore the one that's different . . . ask in the Apache forum.
