I have a Wordpress server running on Apache that produces a number of HTTP 301 redirects. However, while Cloudflare caches page content, it doesn’t seem to cache 301s themselves, meaning any request that hits a 301 has to do a round trip to the origin before hitting the cached page in Cloudflare. Below is an example in curl. What is the best way to get Cloudflare to cache 301s?

I have confirmed that the origin does set an Expires header. The wordpress installation is also running the Cloudflare plugin.

Without knowing the actual URL you’re testing, it’s difficult to diagnose. Is there a query string?
Sorry about that - one URL is https://nofap.com/about which 301s to https://nofap.com/about/. No query strings though.
That must be something about APO. I use a Worker for my site caching, and it’s similar to how APO works, but it caches my 301 request:
Ah, here’s the explanation:
origin,resnok. Page is served from origin, origin returned non 200 status, we cache requests with 200 status only.
My advice would be to use Bulk Page Redirects if you don’t want those hitting the origin.

Gotcha, so this would be a hard coded list of redirects, not cached from the origin per se? Alternatively, can you combine workers with APO?
Yes.
Search function here says yes.
