If I could _enforce_ caching by traffic interception then I could construct vaguely logical cache structures as an ISP.
AS378 does exactly that. It blocks port 80 to abroad and forces everyone to the Netscape proxy servers it runs (2 of them in a load balance fashion with DNS set to point to only one if the other fails). AS378 is the Israeli University academic network of 7 universities.
But relying on users to configure their end systems with the identity of the closest cache server using some ill defined "network metric" is always going to be an erratic affair at best.
Not unless you don't have a choice :-) Go to: http://www.tau.ac.il/Shiber/May96/13May96 There you will find their numbers for yesterday. Port 80 now consumes 54% of all traffic.
