- Extended the documentation talking about it
- Initialize members in the header rather than in the ctor
- Some formatting changes
- Prefer connect-ing to QNetworkReply rather than QNAM for sslErrors
- Because we didn't use the QNetworkReply* argument
- Put the QNetworkReply pointer in a managed pointer
- Removed the code explicitly handling a redirect (it's the new default)
- Edited HttpWindow::httpFinished so that there're less places to reset
the reply pointer
- Updated some ifdefs I didn't update when I was revamping this example
