Expire headers for minified JS and CSS files

  • The description says that this plugin sets Expire headers for minified JS and CSS files.

    How do I check that this is working? When I test my website on webpagetest.org is downloads the minified css & javascript everytime, so it seems to me that it is being downloaded every time – so maybe the expire header is not working?

  • If a response includes a Cache-Control field with the max-age directive, that directive overrides the Expires field. It’s possible your web server could be included them.

    You can use something like HTTP Analyzer or Firebug to see the headers. Or you can also visit one of many online sites to check and see your page’s returned headers.
