I don't know about Yahoo, but one technique for static data is to run Squid or similar on multiple machines, with the Squid proxies obtaining the data they cache from a single master machine. I know one host that does this. What I don't know is how they force changes on the master machine to propagate more or less instantly to the caches. -- Graeme Tait - Echidna To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
