How to Configure Apache to Gzip Your Components
Compressing your Web components will help speed up your Website. The majority of your visitors will benefit as most all Web browsers support gzip compression. You’ll want to compress all text, which includes html, css, javascript, xml, json, etc.
Apache 2.x uses mod_deflate, and all you need to do is add the following to your <VirtualHost> section of your Apache configuration:
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/javascript application/x-javascript
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
All you truly need is the first line. The BrowserMatch lines are there to handle issues with old browsers.

Adding the “AddOutputFilterByType” line to your Apache config file (usually httpd.conf or apache2.conf) is all you have to do. It’s the only step. You don’t actually have to gzip your files — Apache takes care of that for you.
This is great! Thanks!
