URL - Uniform Resource Locator

Web browsers request pages from web servers by using a URL.
The URL is the address of a web page, like: http://www.w3schools.com.

URL Encoding

URLs can only be sent over the Internet using the ASCII character-set.
Since URLs often contain characters outside the ASCII set, the URL has to be converted into a valid ASCII format.
URL encoding replaces non ASCII characters with a "%" followed by two hexadecimal digits.
URLs cannot contain spaces. URL encoding normally replaces a space with a + sign.
