What is WordPress WP Super Cache Plugin?

WP Super Cache is a popular WordPress cache plugin that can help improve the speed and performance of your WordPress website.

How it works

WP Super Cache works by generating static web pages from your dynamic WordPress blog. After a static page is cached our web servers will display these pages to your visitors in place of the cached dynamic page. Static files use less server resources than resource-heavy WordPress PHP scripts, resulting in faster loading pages.

WP Super Cache will allow your website to handle more visitors and will greatly improve your site speed by reducing load times.

Ecenica recommends using WP Super Cache on all of your WordPress websites or blogs.

Whilst there are other WordPress caching plugins available, WP Super Cache is our recommendation as the best WordPress caching plugin. WP Super Cache offers simple and easy setup, great reliability and has that ‘just works’ factor.

Rejected User Agents

We recommend not changing the default values for Rejected User Agents in your WP Super Cache plugin settings.

The Rejected User Agents setting tells your WP Super Cache to only generate caches for pages viewed by real visitors rather than search engine bots. This boost your site’s performance by preventing WP Super Cache from using your server resources to create caches of files that would would most likely never be viewed by your real visitors.

For example, if you’ve installed the WP-Calendar plugin, your blog visitors are more likely to be looking at events in the near future, rather than past events. A search bot won’t make the same distinction and simply crawl through your entire calendar. One event after another. Creating cached pages of events that will not be viewed is a waste of server resources so Rejected User Agents setting tells WP Super Cache to not create a cache.
