What is URL Decoding?

URL decoding is the process of taking an encoded URL string and converting it back to its original format. This is necessary when a URL has been encoded for transmission over a network or for storage in a database, and then needs to be decoded for further processing.

One of the main use cases for URL decoding is in web development. When a web server receives a request for a specific URL, it needs to be able to understand the request and determine which resource the client is requesting. If the URL has been encoded, it will not be able to do this and the request will not be processed correctly. URL decoding allows the server to understand the request and respond with the correct resource.

Another use case for URL decoding is in forms. When a form is submitted, the data is encoded to ensure that it is transmitted correctly. However, the server needs the data in its original format in order to process it. URL decoding allows the server to decode the form data and process it as intended.

URL decoding is also used when working with cookies. If a cookie contains special characters, they may be encoded to ensure that the cookie is transmitted correctly. URL decoding allows the server to understand the cookie and read its value.

URL decoding is also used in OAuth and OpenID Connect protocols to decode special characters in redirect URIs and other parameter values.

URL decoding is also used when the URL has been encoded for storage in a database or for other purposes and needs to be decoded for use in a specific application or script.

It's worth noting that, URL decoding is a reversible process, the decoded data can be easily encoded again to its encoded format, and that URLs are case-sensitive, so special care must be taken to ensure that the decoding process preserves the case of the characters in the URL.
