Wrong header "Connection" value

[FStefanni]

Hi,

I have noticed this behavior:

1. If I post with header "Connection", the corresponding header is sent (OK)
2. If I post with unchecked "Connection" header, the header is nevertheless sent with value close (wrong). In this case it should not be sent, or at least sent with a correct default value, which changed from HTTP1.0 and HTTP1.1 and HTTP2:
   • As ref please see https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Connection
   • In HTTP 1.0 it was close
   • In HTTP 1.1, the connection is kept-alive as default behavior
   • In HTTP2 the header should not be sent at all

Regards
