Decode URLs to understand what data is being passed.
URL encoding (also called percent-encoding) converts characters into a format that can be transmitted over the Internet. Special characters like spaces, ampersands, and non-ASCII characters are replaced with a percent sign (%) followed by their hexadecimal value. For example, a space becomes %20 and an ampersand becomes %26. This ensures URLs remain valid and data is transmitted correctly.
