If not empty - Enable response validation by text which you type. Response will be valid is this string was found in response body. Also support Regexes (Regex builds through Javascript RegExp).


Swap - Swaps the judge url after each request, for acceleration and keep min server busy. If disabled - uses judge with min response timeout.
