I guess the problem with the CNet channel is that it checks for the IP of request... and it must be from an AvantGo server.
The URL that AvantGo uses is:
http://pshost.avantgo.net/channels/cnet/index.html
but if you try to use it, it never loads (at least that's what happen on my PC).
I tought than the UserAgent was the problem, so I switch it to:
Mozilla/4.0 (compatible; Avantgo 5.2; FreeBSD)
but it never loads... that's why Im guessing about the IP/server combination.
And that's the reason of creating this channel at TuPalMX:
