URL

Uniform Resource Locator ( also refered to as a URI though not exactly the same)

  protocol://dns.address:port/path/to/requested/information

• Protocol:// - This is most commonly http://, https:// or ftp://. But can be smb://, afp://, rss://, etc.
  • Please note that file:/// is used in places and the extra / refers the root of the local file system
• dns.address - Is either a fully qualifed domain name (FQDN) or can be a short domain name if your local name service resolver is configured to try certain sub domains.
• :port - Is always optional and is always a numeric value, eg. :8000
• /path/to/requested/information - This is optional but most of the time you will see some path information appended to your [URL]
