* fix 401-302-401-302-429 loop * don't logout users on bad form key, just treat the request as unauthenticated * Handle None/empty case in validate_formkey. A supplied empty formkey, or the lack of a supplied formkey (None) is not a valid formkey. Handle this inside the function rather than at the call-site. * Validate as false if no hashstr or string Co-authored-by: Snakes <104547575+TLSM@users.noreply.github.com>
