ActivityPub extension

Hey hey 👋

I am a developer of the ActivityPub plugin for WordPress and I would love to improve the compatibility between the plugin and W3 total cache. ActivityPub uses content negotiation to have the same URL for users and as API: https://www.w3.org/TR/activitypub/#retrieving-objects

As a result, users often see JSON files in the browser, because these were accidentally cached instead of the HTML file and vice versa.

Is there an easy way to change for example the cache key based on the Accept header or does W3TC support the Vary header?

FYI: We already discussed that there https://github.com/Automattic/wordpress-activitypub/issues/1851
