### TLS Handshake Start { #tls-handshake-start }

The browser would then communicate with that IP address on **port 443** (the HTTPS port).

The first part of the communication is just to establish the connection between the client and the server and to decide the cryptographic keys they will use, etc.

	if req == nil {
		return ""
	}

	if _, port, err := net.SplitHostPort(req.Host); err == nil && port != "" {
		return port
	}

	if req.TLS != nil {
		return "443"
	}

	return "80"

### Início do Handshake TLS { #tls-handshake-start }

O navegador então irá comunicar-se com esse endereço IP na porta 443 (a porta HTTPS).

A primeira parte dessa comunicação é apenas para estabelecer a conexão entre o cliente e o servidor e para decidir as chaves criptográficas a serem utilizadas, etc.
