Though actually, I am using gzip for compression and I am actually serving both XTHML 1.1 with the application/xhtml+xml content-type, and plain text/html for microsoft browsers that can’t handle it.

I do have mod_deflate turned on for my javascript and css files though.

You aren’t using a FilesMatch but other than that I couldn’t tell you, it depends on your server, configuration, and modules.

This really won’t make that much of a difference to begin with but you can use the http header viewer tool by requesting directly your .css or .js file with this .htaccess compression code on and then with this code off and you should see a difference unless something on your end isn’t working correctly.

My .htaccess file:

# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# END WordPress
 
#12 Months
 
Header set Cache-Control "max-age=29030400, public"
 
Header unset ETag
FileETag None
 
# 2 HOURS
 
Header set Cache-Control "max-age=7200, must-revalidate"
 
SetOutputFilter DEFLATE

I am not getting an error. It is just not working with the css and js according to yslow. I was able to set a php.ini file to gzip the php. Although, I am not sure how to do the same thing for the css/js.

Sounds like you don’t have mod_deflate. I need more info like error messages, how you know its not working, and current .htaccess if I were going to answer.
