HTTP headers | Host
The HTTP Host represents the domain name of the server. It may also represent the Transmission Control Protocol (TCP) port number which the server uses. Defining the port number is optional, the default value is considered. For example, “80” is assigned as the port number for an HTTP URL when there is no port number specified. The HTTP Host header is a request type header. The host header field must be sent in all HTTP/1.1 request messages. If a request message does not have any header field or more than one header field, a 400 Bad Request is sent.
