I would like to be able to add a redirection URLs with regexp patterns.
the changes will be in RedirectUtils.matchesRedirects
`

private static String matchesRedirects(Set<String> validRedirects, String redirect, boolean allowWildcards) {
    logger.tracef("matchesRedirects: redirect URL to check: %s, allow wildcards: %b, Configured valid redirect URLs: %s", redirect, allowWildcards, validRedirects);
    for (String validRedirect : validRedirects) {
        if ("*".equals(validRedirect)) {
            // the valid redirect * is a full wildcard for http(s) even if the redirect URI does not allow wildcards
            return validRedirect;
        } else if (validRedirect.startsWith("^") && validRedirect.endsWith("$")) {
            try {
               if (Pattern.matches(validRedirect, redirect))
                    return validRedirect;
            } catch (Exception e) {
                logger.error("(skipped) failed using regexp to filter redirect : " + validRedirect + ", " + redirect, e);
            }
        } else if (validRedirect.endsWith("*") && !validRedirect.contains("?") && allowWildcards) {
            // strip off the query or fragment components - we don't check them when wildcards are effective
            int idx = redirect.indexOf('?');
            if (idx == -1) {
                idx = redirect.indexOf('#');
            }
            String r = idx == -1 ? redirect : redirect.substring(0, idx);
            // strip off *
            int length = validRedirect.length() - 1;
            validRedirect = validRedirect.substring(0, length);
            if (r.startsWith(validRedirect)) return validRedirect;
            // strip off trailing '/'
            if (length - 1 > 0 && validRedirect.charAt(length - 1) == '/') length--;
            validRedirect = validRedirect.substring(0, length);
            if (validRedirect.equals(r)) return validRedirect;
        } else if (validRedirect.equals(redirect)) return validRedirect;
    }
    return null;
}
