What is URL Encoding?
URL encoding, also known as percent-encoding, replaces special characters in a URL with a percent sign followed by their hexadecimal representation. This ensures that URLs are transmitted correctly over the internet, since certain characters have special meanings in URLs (such as &, =, and ?).
