The new "trace" dump flag attaches a net/http/httptrace ClientTrace to each HTTP transaction and logs the connection level events - DNS resolution, TCP connect, TLS handshake (including the negotiated TLS version, cipher, ALPN protocol and server certificate), connection reuse, request write and time to first response byte. Each line is tagged with the time elapsed since the start of the transaction and the request pointer so it can be correlated with the other dumps. This is complementary to the existing dump flags: it shows how the connection behaved rather than what was sent, which is useful for debugging connectivity, DNS, TLS, proxy and keep-alive problems.
