    Description

      After aborting a FTP download (QNetworkReply::abort()), all subsequent requests to the same URL or to other URLs from the same server fail.

      The only way to have them work again is then to call clearAccessCache() on the QNetworkAccessManager object.

      Attached are source files that demonstrate the issue.
