URI - Authority (User /Host / Port )

About

This page is about the authority part of an URI 1)

Syntax

The authority component of a hierarchical URI is, if specified, either:

server-based

A server-based authority parses according to the familiar syntax 

[user-info@]host[:port]

where:

  • the characters @ and : stand for themselves.
  • user-info is optional and defines the credential (or the scope)
  • host and port defines a endpoint (host)

registry-based

Nearly all URI schemes currently in use are server-based. An authority component that does not parse in this way is considered to be registry-based.
