That's assuming the prefetch has to be perfect. Even fetching the redirect page will cut out one round-trip time (that's 0.2s for international users of US websites, sounds small but remember from User Interfaces 101 that a response time >0.3s is perceived as "slow").

With that in mind, prefetch using the current set of cookies and stop when it requires a cookie to be written. If the user selects the prefetched page then write that cookie and continue.

That means that some pages are "prefetch unfriendly", but that's the case anyway (the discussion about multiple sets of cookies is really about how to work around that unfriendliness).
