in order to reduce the amount of runtime log output. Disconnects
are /very/ common in HTTP, and shoudn't be considered errors.
Change the error level from CONNECT to SOCKET

CONNECT is for "Data transmitted by the CONNECT method",
while SOCKET is for "low-level connections"
switch to a 3 decimals versioning scheme
