HTTP doesn't let you do this reliably. The best thing to do is change
the service so that it returns immediately to acknowledge receipt of the
request. Then just use standard Net::HTTP.

Or just spawn a thread and then have the thread wait for the response.
Be careful, however; Ruby threads are not asynchronous when you're
waiting for IO, unless you're careful to wait in select().

That will wait for the response.

Yes, but you can't do HTTP over UDP; you're misunderstanding the protocol.
