threshold Package threshold contains predicates that can define various request thresholds Examples: * RequestMethod() == "GET" triggers action when request method equals "GET" * IsNetworkError() - triggers action on network errors * RequestMethod() == "GET" && Attempts <= 2 && (IsNetworkError() \|\| ResponseCode() == 408) This predicate triggers for GET requests with maximum 2 attempts on network errors or when upstream returns special http response code 408	Package threshold contains predicates that can define various request thresholds Examples: * RequestMethod() == "GET" triggers action when request method equals "GET" * IsNetworkError() - triggers action on network errors * RequestMethod() == "GET" && Attempts <= 2 && (IsNetworkError() \|\| ResponseCode() == 408) This predicate triggers for GET requests with maximum 2 attempts on network errors or when upstream returns special http response code 408
