HTML URL

HTML Uniform Resource Locators

A URL is a web page address.

A URL can consist of letters, such as “tutorialsbyte.com”, or an Internet Protocol (IP) address: 192.68.25.51.

Most people use the website domain name to access the website, because the name is easier to remember than the number.

URL – Uniform Resource Locator

A web browser requests a page from a web server through a URL.

When you click a link in an HTML page, the corresponding <a> tag points to an address on the World Wide Web.

A Uniform Resource Locator (URL) is used to locate documents on the World Wide Web.

An example of a web page address: https://www.tutorialsbyte.com/html/html-tutorial/ Grammar rules:

scheme :// host.domain : port / path / filename

Illustrate:

• scheme – defines the type of Internet service. The most common type is http
• host – defines the domain host (the default host for http is www)
• domain – defines the Internet domain name, such as tutorialsbyte.com
• :port – defines the port number on the host (default port number for http is 80)
• path – defines the path on the server (if omitted, the document must be in the root directory of the website).
• filename – defines the name of the document/resource

Common URL Schemes

Here are some URL schemes:

URL character encoding

URLs can only use the ASCII character set .

to send over the Internet. Since URLs often contain characters outside the ASCII set, URLs must be converted to a valid ASCII format.

URL encoding uses “%” followed by a two-digit hexadecimal number to replace non-ASCII characters.

The URL cannot contain spaces. URL encoding usually uses + to replace spaces.
