I am not sure how it will work on the heavily cached sites. GET with ActivityPub sends a header that requests a JSON response. But the regular GET needs an HTML response. Most caching plugins ignore the headers after caching.
i'm interested in knowing how this works. are you digging into it?
@davew@mastodon.social I am trying. I will keep you informed. Currently I am facing issues with caching issues. With caching switched off it seems to be working.
