Optimize your site Apache mod_deflate compression

Website compression is a way to save your bandwidth and speed up your website. You may easily apply this deflation to your site by referring to this article.

1. First of all, you should compile mod_deflate to your Apache.
2. Next add the following script to your .htaccess.

# compress text, html, javascript, css, xml:
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript

enable HTTP Compression

Many of the website did teach how to check HTTP Compression, what Apache module is needed, but there are less guide on how to make it done.

Today, Mick Genie will guide you how to make it done.

Firstly, you may need to compile your Apache with mod_gzip and mod_deflate (Actually Apache 1.x needed mod_gzip and Apache 2.x needed mod_deflate, hence you may compile both of them).

Once done, modify your httpd.conf and assume it is located in /usr/local/apache/conf. Add the following line to the configuration file.

<Location />
SetOutputFilter DEFLATE
SetEnvIfNoCase Request_URI  \
\.(?:gif|jpe?g|png)$ no-gzip dont-vary
</Location>

Restart the httpd services.

service httpd restart

The above command from httpd.conf will compress all the files except the .gif, .jpe, .jpeg and .png files.
