There is no need to use an .htaccess file with this plugin; caching is handled by WordPress®/PHP alone. That being said, if you also want to take advantage of GZIP compression (and we do recommend this), then you WILL need an .htaccess file to accomplish that part. This plugin fully supports GZIP compression on its output. However, it does not handle GZIP compression directly. We purposely left GZIP compression out of this plugin, because GZIP compression is something that should really be enabled at the Apache level or inside your php.ini file. GZIP compression can be used for things like JavaScript and CSS files as well, so why bother turning it on for only WordPress-generated pages when you can enable GZIP at the server level and cover all the bases!

If you want to enable GZIP and your site is running on the Apache web server, visit Dashboard -> Comet Cache -> Apache Optimizations -> Enable GZIP Compression?; or to enable GZIP compression manually create an .htaccess file in your WordPress® installation directory (or edit the one that’s already there) and put the following few lines in it. That is all there is to it. GZIP is now enabled!

<IfModule deflate_module>     <IfModule filter_module>         AddOutputFilterByType DEFLATE text/plain text/html         AddOutputFilterByType DEFLATE text/xml application/xml application/xhtml+xml application/xml-dtd         AddOutputFilterByType DEFLATE application/rdf+xml application/rss+xml application/atom+xml image/svg+xml         AddOutputFilterByType DEFLATE text/css text/javascript application/javascript application/x-javascript         AddOutputFilterByType DEFLATE font/otf font/opentype application/font-otf application/x-font-otf         AddOutputFilterByType DEFLATE font/ttf font/truetype application/font-ttf application/x-font-ttf     </IfModule> </IfModule>

If your installation of Apache does not have mod_deflate installed. You can also enable gzip compression using PHP configuration alone. In your php.ini file, you can simply add the following line anywhere: zlib.output_compression = on
