.htaccess force browser side cache

  • 772

I am using .htaccess code like

<IfModule mod_headers.c>
 <FilesMatch "\.(gif|jpg|png|css|swf|php)$">
  Header add "Expires" "Mon, 28 Jul 2014 23:30:00 GMT"
  Header add "Cache-Control" "max-age=31536000"
 </FilesMatch>
</IfModule>

<IfModule mod_expires.c>
 ExpiresActive On
 ExpiresDefault A604800
 ExpiresByType text/css A604800
 ExpiresByType image/gif A604800
 ExpiresByType image/png A604800
 ExpiresByType image/jpeg A604800
 ExpiresByType application/x-shockwave-flash A604800
</IfModule>

The problem is that it still checks the server if the file has been modified and then returns 304 Not Modified. I want it to use cache by default i.e. the local browser cache and not make a round trip to the server at all.

Any suggestions?

apache-2.2 .htaccess

  1. You can't force a client to do what you want. All things given in your configuration are "optional recommendations" for a client. You only have control over the server and have no influence on the client's behavior even if you give them advices.
