Do you know that you cache HTML pages in Cloudflare too? This technique is called Edge level caching. Your entire WordPress site will be hosted in 155+ data centres (edge servers) all around the globe.


If you’re new to Cloudflare, read my post – 10 Benefits of Integrating Cloudflare

How does it Work?

WordPress by default cache your static files like images, CSS, JavaScript etc. But it doesn’t cache HTML pages. Caching HTML pages is risky because the data change very often (I’ll cover how to handle the risks throughout this post)

However, with ‘rules’, you can explicitly tell Cloudflare to cache your HTML pages (aka WP posts, pages, etc)

Cloudflare has 155+ edge servers all around the globe. So once you cache it and when a user visits your WordPress site, the pages will be delivered from the nearest edge server of Cloudflare, not from your origin server

Why you should Cache HTML pages?

Higher TTFB and TTLB

TTFB – Time to First Byte, TTLB – Time to Last Byte

If it’s too technical – The first impression is the best impression!

Basically, its the time required to load the web page. Check the screenshots below

In the first screenshot, Cloudflare is enabled but HTML cache is disabled. You can see the difference

Here is the result of testing TTFB from 14 locations

Less load to Server

By serving everything from Cloudflare, there will be very less load to the server. So you don’t need powerful servers and pay a lot of money to the hosting companies. The only load to the server is when you log in to the admin panel and when there is a new/updated post missing from Cloudflare cache

How to Cache WordPress Pages in Cloudflare?

Before we begin, make sure the ‘Browser Cache Expiration’ in the ‘Caching’ tab is set to ‘Respect Existing Headers’. Otherwise, HTML pages will be also cached in the browser. So when you update something it won’t be seen by the user even if they reload

Ok, let’s do it!

Goto ‘Page Rules’ section of the Cloudflare and add the following rules

Rule 1 – Bypass caching for every request to the admin panel (wp-admin)

Rule 2 – Bypass caching if it’s a preview of post/page

Rule 3 – Cache everything (including HTML, css, js, images etc) in the edge servers for a TTL (time to live)

Things that will BREAK and How to Fix Them

As I mentioned before caching HTML pages are risky. Many dynamic features will not work as expected because it will be already cached by Cloudflare

Here are a few common problems and how to fix them

Admin Bar/ Tool Bar

WordPress shows an admin/toolbar to pages if the user is logged in. But Cloudflare will cache those pages and toolbar will be shown to unknown users too

Solution 1: Hide the toolbar for all users by going to Users -> Your Profile

Solution 2: Use the ‘Solution 2’ mentioned in ‘WordPress Default Comments’

WordPress Default Comments

Everyone can comment, but new comments will not be visible unless you clear the cache

Solution 1: Use 3rd party commenting plugins like Disqus or Facebook Comments

Solution 2: Upgrade to Cloudflare paid plan a set ‘Bypass Cache on Cookie‘ rule that will ignore cache, if someone has commented (or if the user is logged in)

Search Page

Just like WordPress comments, search page is also very dynamic. Caching is not a good idea here.

Solution 1: Add an additional rule that will bypass cache on URL like*

Solution 2: Use an Ajax powered search. Some themes come with ajax search by default

Solution 3: Disable search page. This is what I did. I haven’t seen anyone searching directly in my blog!

Understanding Cloudflare Cache

Cloudflare cache works just like any other CDN, using an HTTP proxy. Once there is a new request it checks whether the requested URL is present in the edge server. If it’s not present, the user will get the response from the origin server. Further requests will be cached by Cloudflare based on the TTL

Different Cache Status

Cloudflare returns a cf-cache-status in every HTTP request. Here are the common status

MISS – Response is missing in the edge server, delivered from the origin server. Next response will be probably a HIT

HIT – Response delivered from Cloudflare edge server

EXPIRED – TTL(Time to Live) is over. Next response will be probably a HIT

Checking Cache Status

In order to test whether caching is working or not, go to and enter your URL

If it’s working correctly you’ll see something like this:

Clearing Cache after Updating Posts/Pages

After integration, all your HTML pages will be cached by Cloudflare. If you add/update a new post/page or any other modifications, Cloudflare will not be aware of it

Luckily Cloudflare comes with an official WordPress plugin that will clear the cache of the corresponding URLs if there is an update

You can also clear cache manually without a plugin by going to ‘Cache’ setting in Cloudflare

I hope that covered everything to cache HTML pages in Cloudflare. I know it’s little hard to set up these. But once you’ve done these, you’re going to get the best performance that no cache plugin or hosting company can provide
