Headers always no-store, no-cache etc for PHP files?
By using content-type in a header directive of the php-file litespeed correctly gzips the file the way I want.
The problem is that litespeed always appends these headers for files ending with '.php'
Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
That makes the browsers reload the file every time and it is rather large.
