Is APO compatible with Litespeed cache?

Hey there,
I just changed my cloud flare plan to PRO and as a result I’m able to use APO ( Automatic Platform Optimization for WordPress), but I’m a little bit confused that would it be possible to use litespeed cache plugin and cloudflare plugin together?

One other post here said it wasn’t compatible, but didn’t elaborate. I use LiteSpeed Cache and a Worker that emulates APO with no problems. LiteSpeed doesn’t have my Cloudflare API key because my Cloudflare plugin purges the Cloudflare cache on updates.

I wonder, why use LS with workers instead of APO? Just curious :slight_smile:

I used Workers before APO came along. And for the same $5, I get workers on all my zones. I don’t have enough traffic to exceed basic Workers limits. And I doubt that I’ll even get to the point where my Workers will exceed the $5 cost of APO per free zone.


A big reason is better fine grain control over caching TTL and what to cache or not.

Only way to know is to try but from what I understand of APO cache, not many existing server/origin side guest full HTML page caching solutions would be compatible with APO. Which is another reason why using own CF Worker caching solution can work with existing server/origin side guest full HTML page caching.

I like @sdayman use my own custom CF Worker guest full HTML page caching which allows it to work with my existing server/origin side guest full HTML page caching.


Thanks and I have another question even may seem so simple, what do you mean by “Worker caching”?
Is it a plugin or a product from CF?

Cloudflare really has just one cache. By default, it caches static files. But you can use a Page Rule to trigger caching for a type of file. Or you can use a Worker to trigger caching for a type of file.

Workers are a bit smarter in that you can check for conditions that have to be met, like a user not being logged in. So if there’s no login cookie, the Worker will enable caching for those requests and set the cache duration.

You can write your own CF Worker caching just like CF APO if you want.
