Disable cache with .htaccess
Simple cache removal through .htaccess:
<IfModule mod_headers.c>
Header set Cache-Control "no-cache, no-store, must-revalidate"
Header set Pragma "no-cache"
Header set Expires 0
</IfModule>
Handy when you want to make sure that a user will always load new files from the server. Will of course also make the initial load of the site slower, so use only when necessary.
