Yes, though the test server currently echoes individual lines ending in
\r\n rather than waiting for an additional \r\n.

For HTTP 1.0, you'd know because it would close the connection.  However,
for phase 1 it should echo back whatever you send (so you know to expect
however many lines you sent), and the instructions state that the client
should close the connection.
