                final int warningHeaderCount = newResponseHeaders.containsKey("Warning") ? newResponseHeaders.get("Warning").size() : 0;
                if (warningHeaderCount > maxWarningHeaderCount) {
                    logger.warn("Dropping a warning header; as their total count reached the maximum allowed of ["
                            + maxWarningHeaderCount + "] set in ["
