Did we remove expires, host and port from the other Http classes altogether,
including tests for that?

expires, host and port was removed from the other classes, but there are still
tests which test expires, host and port when being communicated from client to
server, look for these tests in tests/standalone/src/io/HttpTest.dart.

Okay, good. I just wanted to make sure we didn't break any other tests :)
