This plugin allows your WordPress blog to output pages compressed in gzip 
format if a browser supports compression.
HTTP compression generally means a 60-80% REDUCTION in the size of your pages 
(broadband usage) as well as an INCREASE in download speeds of 3x to 4x.
To test if your blog is using compression use the following link:
http://ismyblogworking.com/
Check “Page GZip” on the right hand size. 
Check “Bandwidth saved by compression” on the left hand side.
NOTE: This plugin should not be used alongside WP Super Cache or WP Cache 
since those plugins are already implementing compression. Your blog 
will keep working but those plugins will stop caching new pages.
RECENT NEWS – 20 March 2010:
Its been reported by a user that there is a conflict 
using WP HTTP Compression together with Google Analytics Plugin (3.2.5). I’ll

the PLUGIN. Google Analytics scripts and stat collection have been tested 
and work fine with the WP HTTP Compression plugin.

With this Plugin you can activate Browser Caching and GZIP Compression on your Apache Webserver. 
With Browser Caching you can tell Browsers when your files usually change, e.g. every month, every week, etc. This will speed up your website because Browser will only make requests to your Server after the declared time. PageSpeed is a Google Ranking Factor so it is important to have a fast website. 
There a several ways to enable Browser Caching. This Plugin uses Expires. The following code will be added to your .htaccess file: 
ExpiresActive On
ExpiresByType text/css “access plus 1 month”
ExpiresByType text/javascript “access plus 1 month”
ExpiresByType text/html “access plus 1 month”
ExpiresByType application/javascript “access plus 1 month”
ExpiresByType application/x-javascript “access plus 1 month”
ExpiresByType application/xhtml-xml “access plus 1 month”
ExpiresByType image/gif “access plus 1 month”
ExpiresByType image/jpeg “access plus 1 month”
ExpiresByType image/png “access plus 1 month”
ExpiresByType image/x-icon “access plus 1 month”
With GZIP Compression your files will be compressed before they get sent to the client. This also makes your Website faster. The following code will be added to your .htaccess file:


Header append Vary User-Agent env=!dont-vary

AddOutputFilterByType DEFLATE text/css text/x-component application/x-javascript application/javascript text/javascript text/x-js text/html text/richtext image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon application/json
