That doesn't make sense. All the DNS SRV lookups on pkg.freebsd.org are done internally to pkg(8), which then issues an HTTP GET to the specific mirror selected by its internal algorithms. The web cache won't see literal 'pkg.freebsd.org' anywhere in the HTTP traffic -- as far as it is concerned, it's a simple HTTP request to a specific mirror 'pkg1.nyi.freebsd.org', and can be cached using the usual processes. What makes it cache unfriendly is that as far as the web cache is concerned each of the different mirrors appears to be completely independent of the others. So at the moment the chance of getting a cache hit is reduced by a factor of three because of the traffic distribution across the three mirrors. Cheers, Matthew -- Dr Matthew J Seaman MA, D.Phil.
