I have just added, or tried to add, gzip compression to my website in order to make it faster. This is the code I have put into .htaccess
<IfModule mod_deflate.c>
#The following line is enough for .js and .css
AddOutputFilter DEFLATE js css
#The following line also enables compression by file content type, for the following list of Content-Type:s
AddOutputFilterByType DEFLATE text/html text/plain text/xml application/xml
#The following lines are to avoid bugs with some browsers
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
</IfModule>
So now I'm using a firebug extension called PageSpeed to monitor gzip compression and it is not working. I also use http://gtmetrix.com/ and the results are the same. Can anyone explain to me what more I have to do to enable gzip compression? Big thanks!
