With luck you'll only have to fake the exact results in your POST. Will less luck you'll need only to scan the HTML for values to be included. With my luck you'll have to download other files that apply call-home schemes to record what you're doing and provide a secret of the day.
Doug,
Thanks for getting back to me so soon.
When I started work on this nightmare of a problem, the first thing I
did was to use WireShark to intercept the communication between
browser and target hardware. It was the result of this that made me
think this would be possible. I'm relativley new to this area of
programming, perhaps I misinterpreted the output. I thought using
curl I'd be able to fake the HTML post that I intercepted.
I've included the WireShark output below, both the request and the
responce (sorry, the attached xml file is quite large). Does anyone
have any ideas?
cheers
Dave
