URL – Uniform Resource Locator
Internet browsers request pages from web servers by using a URL.
A Uniform Resource Locator (URL) is used to address a document (or other data) on the web.
A web address like https://www.worldofitech.com/html/ follows these syntax rules:
• scheme – defines the type of Internet service (most normal is http or https)
• prefix – defines a domain prefix (default for http is www)
• domain – defines the Internet domain name (like worldofitech.com)
• port – defines the port number at the host (default for http is 80)
• path – defines a path at the server (If discarded: the root directory of the site)
• filename – defines the name of a document or resource
Common URL Schemes
The table beneath lists some common schemes:
|Scheme||Short for||Used for|
|http||HyperText Transfer Protocol||Common web pages. Not encrypted|
|https||Secure HyperText Transfer Protocol||Secure web pages. Encrypted|
|ftp||File Transfer Protocol||Downloading or uploading files|
|file||A file on your computer|
URLs can only be sent over the Internet using the ASCII character-set. In the event that a URL contains characters outside the ASCII set, the URL has be changed over.
URL encoding changes over non-ASCII characters into a format that can be transmitted over the Internet.
URL encoding replaces non-ASCII characters with a “%” followed by hexadecimal digits.
URLs can’t contain spaces. URL encoding normally replaces a space with a plus (+) sign, or %20.
ASCII Encoding Examples
Your `browser will encode input, as indicated by the character set used in your page.
The default character-set in HTML5 is UTF-8.
|Character||From Windows-1252||From UTF-8|
