As the name implies, I’m going to show you a nice way to increase joomla slow speed by adding browser cache to your website. I already said in my other articles, mainly how to fix prestashop slow load, by making use of the user browser cache.

Open the .htaccess file inside your document root of your website and add to the bottom of the file the following rules:
