AWS WAF adds pre-parse text transformations and new text transformations

Today, AWS WAF adds pre-parse text transformations for query arguments and ten new text transformations for use in any rule statement. Both help you normalize request content so that AWS WAF inspects requests the same way your application interprets them. Pre-parse text transformations normalize a raw query string before AWS WAF parses it into key-value pairs, closing HTTP parameter pollution and parser differential evasion gaps.
