Haven't worked on that since, but here is the plan on what I'll do:
- Globally set the SOCKS5 proxy via an environment variable (needs 
https://codereview.qt-project.org/#change,54507)
- Add a new property "networkAccessEnabled" to WebView (which will end up as a 
boolean member in WebPage in the WebProcess)
- In QtNetworkAccessManager::createRequest(), call 
QNAM::setNetworkAccessible(false) if networkAccessEnabled of the originating 
web page is set to false

This way, network requests can be disabled on a per-page basis.

Not sure what to do with WebSockets (SocketStreamHandle class) yet, I don't 
think I can access the originating web page there. I might just 
unconditionally disable streaming sockets for destinations other than 
localhost, as a hacky workaround.

Not sure how upstreamable all this will be, especially considering the work to 
enable the seperate network process.

Regards,
Thomas
