this lesson explain this url structure.
Visual Explain in This Video:
Uniform Resource Locator( URL)
A Uniform Resource Locator (URL) is used to address a document (or other data) on the world wide web. Web browsers request pages from web servers by using a URL.
web address syntax: https://www.safhatehc.com/index.php
Note: URL is another word for a web address. Also URL can be composed of words (safhtech.com), or an Internet Protocol (IP) address (126.96.36.199).
Most people use name instead of IP when surfing, because names are easier to remember for humans than numbers.
In this table we show some schema of URL:
|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. If a URL contains characters outside the ASCII set, the URL has to be converted.
URL encoding converts non-ASCII characters into a format that can be transmitted over the Internet. The URL encoding replaces non-ASCII characters with a “%” followed by hexadecimal digits. Also URLs cannot contain spaces. URL encoding normally replaces a space with a plus (+) sign, or %20.
ASCII Encoding Examples
Your browser will encode input, according to the character-set used in your page. The default character-set in HTML5 is UTF-8.
|Character||From Windows-1252||From UTF-8|
