Support » Plugin: W3 Total Cache » Browser Cache and Header Expires Not Working

  • Hi,

    Thanks for this plugin. It’s really sped our site up.

    However PageSpeed and YSlow say that I am not leveraging browser cache or expires headers at all. They say that all my files are set to expire in 2 hours and that no browser cache exists.

    Here’s a link to my Browser Cache settings. Yes, it’s turned on in the General Settings:

    Below is a snippet of my .htaccess that includes header settings. The rest of the .htaccess file includes redirects and rewrites.

  • I have the same issue, some stuff gets expiry dates some do not.

    +1

    You need to contact your host and see if they will install mod_expires

    Mod mime handles the filetype
    Mod deflate handles the browser cache
    Mod expires handles the expires in header
    Mod header handles the… header

    You have to have them on your server
    a2enmod all of them and restart apache

    Anyway, what Pagespeed complains might be EXTERNAL files, not internal ones
    Though sometimes images don’t get the right expiry date…

    I’ve seen that W3TC htaccess rules are a bit bloated and outdated.
    Time for an update maybe?
