This works in case of POST request by specifying content length header but write only lesser bytes to socket than specified in content length header.

This is needed for compliance with HTTP spec. netcat -v -v 192.168.1.10 8080 POST /api/test HTTP/1.1 User-Agent: curl/7.29.0 Host: 192.168.1.10:8080 Accept: */* Content-Type: applicati...
