Overview
URL encoding, also called percent encoding, represents reserved, unsafe, or non-ASCII characters with a % followed by hexadecimal byte values. For example, characters that would otherwise break a URL can be safely transported through paths, query strings, and form data.
URL encoding appears in query strings, redirects, form submissions, logs, and captured HTTP requests. Analysts need to decode it correctly before judging what a parameter, path, or encoded value actually contains.
In this lab, you practice reading percent-encoded characters in web data, handling reserved characters, and normalizing encoded values before analysis.
