What is the structure of a URL?

The URL structure consists of 3 basic parts.

The URL structure was defined as early as 1994 by the great British computer scientist, Sir Tim Berners-Lee, who created the world’s first web browser. Basically, the url is almost the same as the C:DocumentsPersonalmyfile.txt path in windows, but with some added things to be able to find the correct server address on the internet and use the correct protocol to access information securely.

A URL with full components will include 4 elements including:

Protocols: http, https, ftp,…World Wide Web: www Communication ports: 80, 8090, 443, 2081, 7777,…

To better understand what URL components are, here we will go through a specific analysis of the URL structure.

A simple URL will have 2 main parts, the connection protocol (Scheme) and the provider (Authority).

What is

Scheme in URL

?Many people think that a URL is a web address. However, it’s not that simple. A web address is a URL. But a URL is not just a website address. In addition to the web address, other services you can also access on the internet such as FPT or even MAILTO are URLs.

Where, the Scheme part of the URL (the text before the colon) indicates the protocol by which the application and the server communicate.

There are three main types of Scheme protocols:

Hypertext Transfer Protocol (HTTP): A form of basic web protocol that determines what actions web servers and browsers need to take, in response to certain commands. (HTTPS): Is a form of HTTP that is operated with a security layer, encryption, ensuring information is transmitted more securely. File transfer protocol (FTP – File Transfer Protocol): The protocol used to transfer files over the internet.

With modern browsers like these days, you may not need to use Scheme to access certain addresses, because the browser can automatically determine the appropriate protocol. However, in some cases where it is required, you still have to enter the full protocol.

What is

Authority in URL

?Authority is the part that begins after 2 forward slashes of the protocol. An Authority simply consists of the World Wide Web (www) and the domain name.

Example: “”

As in the example above, this cluster of components, called hostname, is responsible for getting an IP address. If you already know the browser address, you can enter it in the browser address bar instead of the hostname.

URL Authority Analysis:

Domain (top-level domain): As in the example above, the top-level domain is “com”. This is the top level in the domain name hierarchy, used to translate IP addresses into simpler and easier to remember language addresses. These top-level domains are managed by ICANN Domains and Numbers Corporation.

In the world today, there are 3 popular types of top-level domains such as .com, .net, .gov. Countries also have characteristic 2-digit top-level domains. For example: Vietnam is .vn, US is .us, Canada is .ca… Besides, there are some top level domains added such as .museum, .club, life, .news,… however These domain names are quite rare and uncommon, so when choosing a domain name to design a website, users often do not like these domain extensions.

Subdomain (subdomain): As in the example above, both “www” and “facebook” parts are subdomains. In which, “www” is the subdomain of both the “facebook” subdomain and the “.com” top-level domain. Instead of using “www”, many units and organizations can replace it with news.subdomain.domain, or mail, life, etc.

Besides, the Authority of the URL can be more complex and has some other components such as:

Port number: Device use IP addresses to receive information to the appropriate servers on the network. For example: “//”, where “8080” is the IP address, associated with the hostname with a “:” sign.
