Since the proxy requests comes from NodeJS's HTTP 1.1 request client, a
backend server may default to setting Connection: keep-alive in its
response. However, the real HTTP 1.0 client may not be able to
handle that.
Force HTTP 1.0 client's to Connection: close, unless the client
explicitly supports keep-alive.
Since joyent/node@35607f3a2d, https and
tls modules validate server certificate by default. Turn this feature
off since we're using self-signed certificates in tests.
Currently wss tests are still failing, pending investigation.
Commited on a plane from Poznań to Munich.
