HTMLUniform Resource Locator (URL)

URL is a web address.

URLs can be composed of letters, such as "tutorialpro.org", or an Internet Protocol (IP) address: 192.68.20.50. Most people access websites using the website domain name because names are easier to remember than numbers.

Common URL Schemes

Here are some URL schemes:

URL Character Encoding

URLs can only use the ASCII character set to be transmitted 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 two hexadecimal digits to replace non-ASCII characters.

URLs cannot contain spaces. URL encoding typically uses "+" to replace spaces.
