[Interest] Debugging tip for QNetworkReply

[Jason Kretzer]

The zip that fails and is unreadable is a 1k file.  The zip that I am attempting to download is ~55MB.  The 1k zip also cannot be opened by a zip program nor a text editor.  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?

Why is it not readable? Is the file too short? Is it corrupted? Please compare the result with what was supposed to be there.
