How does this work? How do you host pixelfed.domain.com and mastodon.domain.com together in the same domain, with queries for “@[email protected]” to the webfinger host path?
I’m other words, how does the querying application know which resource it needs? How do you know that a pixelfed instance will get the pixelfed resource versus the mastodon resource?
Can you eli5?
I don’t think I understand what you mean.
What would the reverse proxy do in this situation?
