Feature Request: Multisite working as one server

[franckmee]

What

Hello and thanks for your work!

I use a Wordpress multisite installation to manage sites based on their topic.
First site and network management are on domain.ext; other sites are on topic1.domain.ext, topic2.domain.ext, etc.

Currently, when I install ActivityPub, the blog profiles have a different domain for every blog (by default @topic1.domain.ext@topic1.domain.ext, @topic2.domain.ext@topic2.domain.ext, etc.).
Instead, I'd rather use the main domain for all profiles, so I can have feeds/profiles @topic1@domain.ext, @topic2@domain.ext, etc.

Ideally, a consolidated feed for the whole network would also be nice (something like @alltopics@domain.ext).

I am aware this is a niche use case and it might require a lot of work, so I won't be offended if you consider this a very low-priority. ;-)

Thanks for all the work you did and for you very quick response to my earlier bug request.

Why

I use several Wordpress websites for different topics, and it would be convenient if my followers could follow only the topics they are interested in, without having to create several different "activitypub servers".

How

No response

I now understand why it can’t work that way :(

[Jiwoon-Kim]

The only design I can come up with is to enable the Application actor and Person actors only on the main domain.

It might be more feasible to request multi-forum group actors instead.

Even so, it would not be possible to avoid duplicate records in each instance database whenever a comment is posted in a multisite setup.

Using a CDN might improve the situation somewhat from a database management perspective, but personally I think the limitations are still significant.
