Right. Though the details are very sparse, this is stock Squid
running in accelerator mode. The solution I described is quite
different (for one, it's normal-mode squid for _outbound_ requests,
and second, it actually probes the links to see if they're working).
A commercial solution that looks a lot more like the stuff we built
are products by Stonesoft ("Multi-Link Technology") and Fatpipe
("Redundant Array of Independent Lines"). RadWare's "LinkProof" has
a similar style, though the actual technique they use is more link-
centric instead of path-centric.
