We would hope so, because this would mean that a HTTP/1.1 Vary would be able to save round trips often. However, I do not believe that differing profiles are that rare in practice. They are very common behind the shared cache of the cern.ch domain I am currently using. And one would expect even bigger diversity behind a country-level cache. >Using multiple URLs is advantageous because it gives the user agent more >information, and thus more control over how it completes the retrieval, >and also improves load-sharing and mirroring techniques and reduces the >amount of information the client has to send to the server on every >request. I'm confused. Are you talking about the long-term advantages of multiple URLs here? I don't see how you would get these advantages using the current generation of software. > Using a single URL is advantageous because it only requires >one round-trip, assuming the server guesses right. > >....Roy Koen.
