Today we are going to focus on learning how to use WP Super Cache on WordPress blog. There are two great plugins which can be used for caching plugins purpose: WP Super Cache and W3 Total Cache. Depending upon your needs one of them must be enabled on your blog, but today we are only going to discuss how to use WP Super Cache on WordPress blog.
What WP Super Cache do is that it takes your Dynamic WordPress PHP files of your blog and convert them to static HTML files. The benefit of this file is that it is less heavier than the actual PHP file and increase the page load speed which ultimately makes the visitor happy as no one like to wait. With increased page load speed search engines are more likely to index your pages and show them to the potential visitors.
Well most of the above is true but there is a catch, the static HTML file will be served to most of the users except the ones who are logged into your website or has left a comment on your blog. This partiality is because when the user is logged in or has posted a comment on your blog is displayed with their name rather than the static file hence they are handled by legacy caching engine.
Feature os WP Super Cache:
- Allow you to use Content Delivery Network (CDN) along with the caching system.
- Compressed web pages to reduce loading time.
- Caching available for PHP pages also
- Caching also available for mobile devices and tablets.
