[Interest] Debugging tip for QNetworkReply

[Mandeep Sandhu]

A couple of questions to help debug further.

* What platform are you running this on and what's the version of Qt?
* What is the MIME type set by the webserver when responding to your
request (you can check it by dumping the headers received)
* According to the webserver logs, how much data was returned for the
problematic zip file?
* Whats the size of the zip that works?

Is there a way I can tell what the failure is?  Perhaps, I can use wireshark to see the traffic and see the http response codes from the server. They should be 200, I would think since I can use a browser and get the zip(s) that way.  Perhaps a way to look through the request/reply objects to see what is going on?
