The Vixie Interceptor is really the only product on the market that handles this particualr situation correctly - it is a fine product in that respect. Paul and his group - worked thorugh that issue with very fine detail. To the best of my knowledge Digex is using the Inktomi/Alteon solution. On 25 Jun 1998, Paul Vixie wrote:
Odd. The box we used to sell through Mirror Image Internet has no problems reaching Cybercash's site -- though I'll admit that we had a lot of angry customers for a long time while we found all the wierd little unspecified protocol violations that "just work" if no "hijacking" takes place.
I don't think Digex is using one of our boxes, and if they are using one of the "just run Inktomi software on a Solaris box and put an Alteon next to it" then there are going to be some wierd little unspecified protocol violations that only Alteon, and a new protocol between Alteon and Inktomi, could fix. (Our box integrates forwarding and "hijacking" and this is why.)

The box we built was designed for access providers -- you know, put 1,000 modems in a room and sell dialup accounts. It works fine in that context. And, dialup users are usually not terribly deep as technologists, and they are used to having their bits mutilated in the great cause of "overcommit."
While a T1 data rate would present no real problem, a T1 customer who would usually recognize what was happening to them AND care about it, *would* represent a problem. And besides, a T1 customer would probably be willing and able to use ICP or at least run their own local cache and point their browsers at it nontransparently.
