Question

I asked a question about improving CSS load times and one answer suggested setting expire headers on my web page. Can someone explain how I can do this. I’ve never heard about it before.

Answer 1

This is an apache trick you can do by creating a file called ‘.htaccess’ and placing it in the root of your domain via FTP.

<FilesMatch "\.(css)$">
ExpiresDefault "access plus 2 hours"
</FilesMatch>

Paste that in your .htaccess file and it will set the header f r css files. Add more filetypes, (css|js)

or cache-control for non-apache users:

<ifModule mod_headers.c>
  <filesMatch "\\.(css)$">
    Header set Cache-Control "max-age=2592000, public"
  </filesMatch>
</ifModule>

In fact, use all of the tricks your server supports in this article, your site will be noticeably faster:
