ClassicPress .htaccess Hacks for Performance and Security

Rocket your ClassicPress site performance and security with .htaccess – no plugins required!! 100% applicable to WordPress, too!

The following .htaccess directives can help to boost your ClassicPress performance and security. Your existing `.htaccess` file may contain some of these directives already, so, feel free to pick and choose only those that you want. Before adding any directives. head on over to GTMetrix and get your site’s baseline scores – later, after you’ve applied the various directives, you can retest your site to see the improvements in actual numbers.

Getting Started

Make a copy of your existing `.htaccess` file to get started. With the directives below, don’t just do a straight copy/paste! Instead, add one complete directive at a time, refreshing your site in a browser each time to ensure that an Error 500 didn’t occur. If an error did occur, you can delete (or amend) the directive you just added. There are a couple of places where you need to add your own URL, so, be sure to see the comments above each directive.
