Host is a String property that specifies the Internet address or host name of the server accessed by an HTTP
Request for a specified
URL. Host is included in the HTTP
Request as a header field for HTTP 1.1 Requests. Host may also refer to the name or address of a Proxy server when Proxy Connections are used to access the resource identified in
URL. The exact resource identified by an HTTP request is determined by examining both the
URL and the Host properties.
