Apache Cache Setting in .htaccess

Note: Before using .htaccess, you need to ensure AllowOverride All in httpd.conf (maybe I should write a post on this)

Disable cache for all files:

<IfModule mod_headers.c>
   Header unset ETag
   Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
   Header set Pragma "no-cache"
   Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"
 </IfModule>

Disable cache for certain file formats:

<FilesMatch "\.(css|flv|gif|htm|html|ico|jpe|jpeg|jpg|js|mp3|mp4|png|pdf|swf|txt)$"> 	
   <IfModule mod_expires.c> 		
      ExpiresActive Off 	
   </IfModule> 
   FileETag None
   <IfModule mod_headers.c>
      Header unset ETag
      Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
      Header set Pragma "no-cache"
      Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"
   </IfModule>
</FilesMatch>
