Saving Someone’s Day

Following are few steps for HTTP compression on Apache.

• Open httpd.conf
• Uncomment line #LoadModule headers_module modules/mod_headers.so, if it is commented
• At the very end of the file, add following lines

LoadModule deflate_module modules/mod_deflate.so

# Insert filter
SetOutputFilter DEFLATE

# Netscape 4.x has some problems…
BrowserMatch ^Mozilla/4 gzip-only-text/html

# Netscape 4.06-4.08 have some more problems
BrowserMatch ^Mozilla/4\.0[678] no-gzip

# MSIE masquerades as Netscape, but it is fine
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html

# Don’t compress images
SetEnvIfNoCase Request_URI \.(?:gifjpe?gpng)$ no-gzip dont-vary

# Make sure proxies don’t deliver the wrong content
Header append Vary User-Agent env=!dont-vary

• Restart your Apache HTTP server and you are all up and running with compression server output compression.
