Re: ICP_HIT_OBJ

Alexei,

        Seems like what you you may want to do is to finish/polish the
initial implementation of URNs in Squid. IIRC, current implementation
can already return a list of candidate sites (URLs) for a given URN so a
user can pick and choose. Adding response time estimations or ordering
locations by some measure of "goodness" would complete the algorithm. A
good implementation would also try to keep user in the URN space if
possible (something Squid does not do).

The tricky part is how to build the list of candidates, of course; but I
guess you already have more than enough ideas on how to do it.

Alex.
