Web cache deception lab delimiter list

Summary: PortSwigger Research published a delimiter list for its Web Security Academy web cache deception labs, covering the printable ASCII characters from ! through ~ plus their percent-encoded equivalents such as %21, %2F, and %7E. The list sits alongside the topic's other lab material on delimiter discrepancies, delimiter decoding discrepancies, and path mapping discrepancies.

Why it matters: Web cache deception turns your own cache into a store of other users' data, and this list shows how many delimiter characters and encodings an attacker can try against a single cache rule - each one a chance to make the cache file a private response as if it were static.
