dual proxy is the User-agent used by Starband, a satellite internet service provider, and possibly others as well. It is a by-product of their efforts to minimize satellite-link latency; This can be considerable, since the satellite signal has to travel a distance of 22,300 miles four times (89200 miles) in order for a user to request a page and have it delivered to him. Doing the math, that's 480 milliseconds of latency due to air-travel-time of the signal alone. If each page requests several image elements and other client-side-includes, the latency would be horrible.
