How to add Cache-Control (Apache) header depending on content-type?
So far done like this:

<FilesMatch "\.(txt|xml|js|css|svg|gif|png|jpg)$">
    Header set Cache-Control "public, must-revalidate, max-age=864000"
</FilesMatch>

But some scripts are generated dynamically via PHP and sent to the browser, the FilesMatch option doesn't work here...

Answer 1

For those scripts that are automatically generated, the title must be set from php.
