In a vanilla Ubuntu LAMP + virtualmin server, how do i allow cache?

  • 772

I recently set up an Ubuntu 12.04 server with the default LAMP task. Also added virtualmin.

All requests to apache return this in the headers.

Cache-Control:no-store, no-cache, must-revalidate, post-check=0, pre-check=0

How/where do i set cache-control to something more sensible to allow browsers to cache content?

Tried putting this in the .htaccess to no avail. mod_expires is enabled. The result is double Cache-Control headers!

<IfModule mod_headers.c>
  Header add "Cache-Control" "max-age=3600"
</IfModule>
<IfModule mod_expires.c>
  ExpiresActive On
  ExpiresDefault "access plus 3600 seconds"
</IfModule>
apache-2.2

  1. Apparently it was related to me starting a php session.

    Setting session_cache_limiter('public') solved it. You can add it in php.ini or in your script.

  2. Looks like your site generating these headers. Check it's code.
