+    Transfers are aborted if no bytes are transferred before

+    QNetworkRequest::TransferTimeoutPreset. If this function

+    value zero. The request-specific non-zero timeouts set for
+    the requests that are executed override this value. This means
+    that if QNetworkAccessManager has an enabled timeout, it needs
+    to be disabled to execute a request without a timeout.
