   My site throws up a 500 error when I do this. Any suggestions?

   My site ALSO throws an Error 500.
   I can’t see a problem with the code, so something has to be set at the server to accept this, right?

   If you get an 500 internal server error, means that your server don’t have mod_expire.so and mod_headers.so loaded. Edit your httpd.conf and add these lines :

   LoadModule expires_module /usr/lib/apache2/modules/mod_expires.so
   LoadModule headers_module /usr/lib/apache2/modules/mod_headers.so
   

   Cheers

   When I added the above code, I was given an internal server error. I am not sure why? Any suggestions?

   Header set Cache-Control "max-age=29030400, public"
    
   Header unset ETag
   FileETag None
    
   SetOutputFilter MOD_DEFLATE

   @ All

   Sorry for the delay people, I just updated the code to prevent the 500 error, which is telling you that you don’t have the deflate module. At least now you know which module you are missing!

   <IfModule mod_deflate.c>
   <FilesMatch "\.(js|css)$">
   SetOutputFilter DEFLATE
   </FilesMatch>
   </IfModule>

   I am trying to add gzip compression for a friends site which is WP. I already set up compression for php files using php.ini. However, I can’t get the js|CSS to work. Any suggestions. The site is hosted with Godaddy, apache of course.

   @ jason ~

   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.

   Thanks for your attention:

   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.
