Swaps QHttpServerResponder other with this QHttpServerResponder. This operation is very fast and never fails.

This function was introduced in Qt 6.8.

void QHttpServerResponder::write(QHttpServerResponder::StatusCode status = StatusCode::Ok)

Answers a request with an HTTP status code status.

Note: This function sets HTTP Content-Type header as "application/x-empty".

void QHttpServerResponder::write(const QHttpHeaders &headers, QHttpServerResponder::StatusCode status = StatusCode::Ok)
