I see, well I guess the real question is whether it can be improved at the server/protocol level and my answer is I don’t know. There’s some handshaking that clearly has to occur between your instance and the other instance to load the initial community state and I don’t know where that process can be optimized. I think I’ve seen people mention tools that have been created to automatically subscribe a dummy account on your instance to all the communities on the largest instances to kind of bootstrap the process for other users, but I don’t have a link to such a tool handy.

Edit, and there’s never going to be a guarantee that your server can talk to their server until you try clicking the link because the other server could be overloaded, down, or blocking your server.

What you’ve described is exactly how it’s supposed to work. Once a user has subscribed to an external community from your instance, it should load immediately for any users afterwards.

You can run headless or do what the person I was responding to recommended and put it behind an authenticated portal, but that’s not really going to stop other instances and clients from accessing the same resources that op is hoping to limit access to except in the most basic case of people casually browsing op’s Lemmy instance through op’s own lemmy-ui.

Edit, but to be clear, what I was responding to and my response didn’t directly address op’s specific concern (which I kind of misunderstood myself before just now rereading) that outside/guest users shouldn’t be able to search for communities from other instances and I think it’s a fair concern because just searching for a community from another instance brings in posts and could be a vector for spam/abuse.

Wouldn’t this do basically nothing to prevent a 3rd party client from browsing your instance without authentication? I don’t know that there’s much that can really be done about this because you need open APIs for other instances to be able to access the content of your instance in order to make federation possible. That said, it’s an important consideration that anybody running a single person instance should consider. If you run a single person instance, people can learn a lot about you just by seeing which communities are available on your instance. The only way to obfuscate your actual interests is to have a dummy account subscribe to all the top communities on the biggest instances. (Which, honestly, this isn’t a bad strategy to employ anyway if you’re wanting a fresh All feed).
