Remove support for multiple connection in a single server

[hueniverse]

hapi is (probably) the only framework that supports adding multiple ports to a single server instance. This was done for two use cases:

• Support an internal process admin channel (serve normal API over port 8000 and allow internal admin access on port 8001)
• Run multiple services in a single process for testing purposes (run a single server that have both your "login" and "billing" APIs, each on a different port)

At this point, external tools would do as good a job at allowing you to manage multiple servers, each with a single port.

I’m working heavily with hapi for several years now, I can’t recall a single situation where we had depended on the multiple connections. On the other side, I do recall it being a bit confusing when starting to work with hapi. If you were to remove this feature, I think the onboarding would be much easer. Big +1 from me 💯

Would still be possible to spin up another server instance in the same process, no?

[hueniverse]

@kpdecker yep. Just need to reuse the config.

O agree 100% with @gr2m, I think the cognitive overload of multiple connections is not worth It.

I’ve used this before and found it handy for the reasons outlined, but the workaround in #3572 (comment) would be more than acceptable.

I too agree that the initial setup simplification alone is worth removing that feature.

We use this feature all the time to redirect http requests on port 80 to use ssl

I find it useful. I love that you can load plugins per connection. One use case is private routes for cache invalidation.

I like the possibility to load plugins for specific connections, too. Is there any other way to restrict the effect of a plugin to certain routes or path-prefixes (e.g. a plugin should only affect /admin/* routes)?

[hueniverse]

@Mattii You just just losing the ability to select connections because there is always just one. The rest of the plugin options remain.
