When in proxy server mode on Win7, ncat immediately responds to a new connection with HTTP/1.0 400 Bad Request. This HTTP response happens before the client submits any data.

C:\>ncat -vvv -l --proxy-type http
Ncat: Version 7.70 ( )
NCAT DEBUG: Initialized fdlist with 2 maxfds
Ncat: Listening on :::3128
NCAT DEBUG: Added fd 96 to list, nfds 1, maxfd 96

The same behavior is not observed on Linux.
