Of course. However you have to consider the implementation effort for an infinitesimal gain. And in practice it'll be almost completely useless. If the machine is not memory constrained or if requests are very frequent it'll stay in cache and the redirector doesn't need to do anything special. If it is under pressure and/or requests are not frequent the cache will have a short lifespan (here it's 1 or 2 minutes at most), so sending it again to the same mirror will have no benefit. Anyway, asking for no matter what feature is free... --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
