Comment(by Denis-de-Bernardy):

 Still, it causes tremendous amounts of problems on some servers, and this
 is really something you want to deal with from apache. In your htaccess
 file, add:

 {{{
 <IfModule mod_deflate.c>
 # Insert filters
 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
 AddOutputFilterByType DEFLATE application/x-httpd-php
 AddOutputFilterByType DEFLATE application/x-httpd-fastphp
 AddOutputFilterByType DEFLATE image/svg+xml

 # Drop problematic browsers
 BrowserMatch ^Mozilla/4 gzip-only-text/html
 BrowserMatch ^Mozilla/4\.0[678] no-gzip
 BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html

 # Make sure proxies don't deliver the wrong content
 Header append Vary User-Agent env=!dont-vary
 </IfModule>
 }}}

 Doing so is a lot less resource intensive that php's ob_gzhandler, it's
 much faster, and it avoids potential double compression problems.
