When typing http://nova-tv:8080/ the URL is changed automatically to http://www.nova-tv.com:8080/ which also fails. The wanted behavior is to not change the URL in this case. This happens when the page we are looking for is https://nova-tv:8080/ Also I don't think we want to change the DNS when the previous one actually resolve. I mean, if nova-tv DNS entry resolves, we don't want to fix it to www.nova-tv.com

Would also need this behaviour to be implemented as it is pretty annoying on a development environment. I would even suggest that the initial URL is preserved if all of the alternatives tried failed (regardless of DNS resolution). I realise the bug is 3 years old but I'd hope someone could pick it up ;)

we don't change a typed url, the only thing we may guess differently is the presence of www., that will be improved with bug 1239708
