I am currently planning a caching scheme for URL's as our network
operators are concerned about the cost of all this traffic - we
pay $$ per megabyte received. The basic idea is to have a UDP
server for managing the cache while data transfer to/from the cache
is done via nfs. The cache server just serves file names.
Even a simple scheme looks like offering a good pay-off. The Expires:
header can be used to override admin defaults for purging the cache.
