Now, what is a "Layer1 router"?

Opera's claim is from analytics of its Opera Turbo system - which is
an Opera-owned proxy that sits between Opera Mini and the actual
website and takes up a bunch of processing (including running
javascript).

And what about case 3: Where a custom build of Opera Mini, based upon
a private label deal between Opera and Nokia, is the built-in browser
on the handset (as is the case in the Nokia 6303)?

Counting total HTTP requests obviously depends on whether Statscounter
or whoever gets to see the request; Opera Mini in Turbo mode
apparently doesn't allow them to do so.
