<protocol>//<hostname>:<port>/<pathname><search><hash>
  • protocol: Specifies the protocol name be used to access the resource on the Internet. (HTTP (without SSL) or HTTPS (with SSL))
  • hostname: Hostname specifies the host that owns the resource. For example, www.eyehunts.com. A server provides services using the name of the host.
  • port: A port number used to recognize a specific process to which an Internet or other network message is to be forwarded when it arrives at a server.
