WP Cloudflare Super Page Cache – WordPress plugin
The free Cloudflare plan allows you to enable a page cache by entering the Cache Everything rule, greatly improving response times.
However for dynamic websites such as WordPress, it is not possible to use this rule without running into problems as it is not possible to exclude critical web pages from the cache, the sessions for logged in users, ajax requests and much more.
Thanks to this plugin all of this becomes possible.
You will be able to significantly improve the response times of your WordPress website by taking advantage of the very fast Cloudflare cache also for HTML pages, saving a lot of bandwidth. The alternative to this plugin is to purchase and configure the Enterprise plan.
This plugin is 100% jQuery free and compatible with all versions of WordPress and all WordPress themes. It can also be used in conjunction with other performance plugins – such like Autoptimize and LiteSpeed Cache – as long as their rules do not interfere with the Cloudflare cache.

How do I know if everything is working properly?
To verify that everything is working properly, I invite you to check the HTTP response headers of the displayed page in Incognito mode (browse in private). WP Cloudflare Super Page Cache returns two headers:
If its value is cache, WP Cloudflare Super Page Cache is active on the displayed page and the page cache is enabled. If no-cache, WP Cloudflare Super Page Cache is active but the page cache is disabled for the displayed page.
This header is present only if the previous header has the value cache.
If its value is 1, the displayed page should have been placed in the Cloudflare cache.
To find out if the page is returned from the cache, Cloudflare sets its header called cf-cache-status.
If its value is HIT, the page has been returned from cache.
If MISS, the page was not found in cache. Refresh the page.
If BYPASS, the page was excluded from WP Cloudflare Super Page Cache.
If EXPIRED, the page was cached but the cache has expired.
Do you allow to bypass the cache for logged in users even on free plan?
Yes. This is the main purpose of this plugin.
What is the swcfpc query variabile I see to every internal links when I’m logged in?
It is a cache buster. Allows you, while logged in, to bypass the Cloudflare cache for pages that could be cached.
Do you automatically clean up the cache on website changes?
Yes, you can enable this option from the settings page.
Can I restore all Cloudflare settings as before the plugin activation?
Yes, there is a reset button.
What happens if I delete the plugin?
I advise you to disable the plugin before deleting it, to allow you to restore all the information on Cloudflare. Then you can proceed with the elimination. This plugin will delete all the data stored into the database so that your WordPress installation remains clean.
What happens to the browser caching settings on Cloudflare?
You will not be able to use them anymore. However, there is an option to enable browser caching rules
Does it work with multisite?
Yes but it must be installed separately for each website in the network as each site requires an ad-hoc configuration and may also be part of different Cloudflare accounts.
Can I use this plugin together with other performance plugins such like Autoptimize, WP Rocket or W3 Total Cache?
Yes, you can. Read the FAQ section into the settings page for further information
Something is not working, what can I do?
Enable the log mode and send me the log file and the steps to reproduce the issue. Make sure you are using the latest version of the plugin.
Have been using the CF worker-rocks!
Thanks a lot !
I have been using it for a few months and satisfied with the result. The support section here is excellent. Developer responds very quickly. Thanks
It makes my website like a rocket!
Thanks a lot!
Huge difference on GTmetrix with this plugin enabled and configured. It’s like Clouflare was not working well without this plugin. thanks
I haven’t had the plugin very long, it has definitely improved my site.
Seems very well written, has a plethora of configuration options for power users (and with great explanations too). The official Cloudflare WordPress plugin (or any other caching plugin with “Cloudflare integration”) is a joke compared to this.
Kudos to the developer for making and keeping this free. I urge everyone who uses this in profitable projects to donate. This plugin is a rare gem.
