Gzip Content Through .htaccess for Suported Browsers

Compress all files through .htaccess

Here’s a few more tips to speed up your joomla website through your .htaccess file.

Borrowed from the magento standard .htaccess, which contained some nice code to compress, or not compress depending on the user agent calling for the page.

The lines look like this, and can be added to the bottom of your file:

############################################## enable apache served files compression## http://developer.yahoo.com/performance/rules.html#gzip# Insert filterSetOutputFilter DEFLATE# Netscape 4.x has some problems…BrowserMatch ^Mozilla/4 gzip-only-text/html# Netscape 4.06-4.08 have some more problemsBrowserMatch ^Mozilla/4.0[678] no-gzip# MSIE masquerades as Netscape, but it is fineBrowserMatch bMSIE !no-gzip !gzip-only-text/html# Don’t compress imagesSetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary# Make sure proxies don’t deliver the wrong contentHeader append Vary User-Agent env=!dont-vary# enable resulting html compressionphp_flag zlib.output_compression on

This relies on you having mod_deflate and zlib support. You can check that with an info.php file.
