5. Optimistic data
Tor allows SOCKS clients to send connection data before Tor has sent a
SOCKS response. When using an exit node that supports "optimistic data",
Tor will send such data to the server without waiting to see whether the
connection attempt succeeds. This behavior can save a single round-trip
time when starting connections with a protocol where the client speaks
first (like HTTP). Clients that do this must be ready to hear that
their connection has succeeded or failed _after_ they have sent the
data.
