Header lines add exact name and value pairs after the request line.

Headers are name and value lines

After the request line, each header line has a name, a colon, and a value.

\text{name: value}

The Host header value is net.example.

\text{Host}=\text{net.example}

The Accept header value is text/html. It asks for a response type, not a virtual host.

\text{Accept}=\text{text/html}

Headers add named details after the request line. The Host header is the one used for this routing choice.
