ServiceNow Incoming REST Response: handling large response with pagination

example looping through each page of the request data set

        var r = new sn_ws.RESTMessageV2('<rest_msg_name>');
        var header = r.getRequestHeader("Accept");
        var authorization = r.getRequestHeader("Authorization");
        r.setStringParameterNoEscape("aParam", aParam);
        r.setQueryParameter('aParam2', aParam);
        r.setQueryParameter('per_page', '20');
        r.setQueryParameter('page', '1');
        var resp = r.execute();
        var responseBody = resp.haveError() ? resp.getErrorMessage() : resp.getBody();
        var httpStatus = resp.getStatusCode();
                
        var objC = JSON.parse(responseBody);
        var cPagiNation = objC.pagination.pages;

        for (var cP = 1; cP <= cPagiNation; cP++) {

            var r2 = new sn_ws.RESTMessageV2(restName, '<rest_msg_name>');
            var header = r2.getRequestHeader("Accept");
            var authorization = r2.getRequestHeader("Authorization");
            r2.setStringParameterNoEscape("aParam3", aParam3);
            r2.setQueryParameter('page', cP);
var resp2 = r2.execute();
            var responseBody2 = resp2.haveError() ? resp2.getErrorMessage() : resp2.getBody();
            var httpStatus2 = resp2.getStatusCode();
            
            ...
        }
