[Interest] QNetworkAccessManager put uploads contents twice

[ashish dabhade]

To avoid that I also tested it by removing the authenticationRequired and
passing username and password in the url as per basic auth specs. For eg.
QUrl( "http://user:password@192.168.1.157/webdav/Media/somefile.mp4" ).
This too resulted the same behavior.
Also suppose the file is of large size say for eg. 300 Mb. wouldn't it be
unnecessary to upload so much data twice ?

I tested the same scenario with the now deprecated **QHttp** class and to
the surprise it uploaded the contents just once.

So if the above scenario is due to the design what would be the best way to
handle it ? For smaller files it is fine. I wanted to show the progress bar
for uploading which now fills up twice :)
