URL Encode/Decode
Percent-encoding, also known as URL encoding, is a mechanism for
encoding information in a
Uniform Resource Identifier
(URI) under certain circumstances. Although it is known as URL encoding it is, in fact, used more generally within the main
Uniform Resource Identifier
(URI) set, which includes both
Uniform Resource Locator
(URL) and Uniform Resource Name (URN).
As such, it is also used in the preparation of data of the application/x-www-form-urlencoded
media type, as is often used in the submission of
HTML form
data in HTTP requests.
