Website Compression with mod_deflate
I just added mod_deflate to my server by using the following configuration:
LoadModule deflate_module modules/mod_deflate.so
<IFModule mod_deflate.c>
SetOutputFilter DEFLATE
SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI \.(?:exe|t?gz|zip|bz2|sit|rar)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI \.pdf$ no-gzip dont-vary
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
</IFModule>
The static parts of my pages now render with about 70% compression, meaning that I’m saving 2/3 of static page bandwidth now. Server load seems fine!
