1 - About

This page is about the authority part of an URI


3 - Syntax

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

3.1 - server-based

A server-based authority parses according to the familiar syntax

[[email protected]]host[:port] 


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

3.2 - 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.
