      When using QNetworkAccessManager with QNetworkDiskCache and you receive a 404 error for a network reply and do not call QNetworkReply::readAll(), files are left open.

      When debugging using a QAbstractNetworkCache I see that prepare() is called, but nothing more, but if you call QNetworkReply::readAll() it works as expected.

      This results in the process running out of file descriptors.

      I've tested Qt all the way back to 6.5.6 and it also has the issue.

      See attached test project.
