Overview
A Uniform Resource Locator (URL), colloquially termed a web address, is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it. A URL is a specific type of Uniform Resource Identifier (URI), although many people use the two terms interchangeably. URLs occur most commonly to reference web pages (http) but are also used for file transfer (ftp), email (mailto), database access (JDBC), and many other applications.
History
Uniform Resource Locators were defined in RFC 1738 in 1994 by Tim Berners-Lee, the inventor of the World Wide Web, and the URI working group of the Internet Engineering Task Force (IETF), as an outcome of collaboration started at the IETF Living Documents birds of a feather session in 1992.
The format combines the pre-existing system of domain names (created in 1985) with file path sy…
Syntax
Every HTTP URL conforms to the syntax of a generic URI. The URI generic syntax consists of a hierarchical sequence of five components:
where the authority component divides into three subcomponents:
This is represented in a syntax diagram as:
The URI comprises:
Internationalized URL
Internet users are distributed throughout the world using a wide variety of languages and alphabets and expect to be able to create URLs in their own local alphabets. An Internationalized Resource Identifier (IRI) is a form of URL that includes Unicode characters. All modern browsers support IRIs. The parts of the URL requiring special treatment for different alphabets are the domain name and path.
Protocol-relative URLs
Protocol-relative links (PRL), also known as protocol-relative URLs (PRURL), are URLs that have no protocol specified. For example, //example.com will use the protocol of the current page, typically HTTP or HTTPS.

Notes
1. ^ A URL implies the means to access an indicated resource and is denoted by a protocol or an access mechanism, which is not true of every URI. Thus http://www.example.com is a URL, while www.example.com is not.
2. ^ The procedures for registering new URI schemes were originally defined in 1999 by RFC 2717, and are now defined by RFC 7595, published in June 2015.
