Hello Brian, Tuesday, December 05, 2000, 9:08:41 AM, you wrote: BM> With just two systems, running squid on one machine to access the BM> second is a decent solution. This has the advantage of being BM> completely self-updating and trivial to maintain. VERY interesting. Do i have to setup squid to listen on port 80 instead of 3128 for this? Or are they any other configuration tips somewhere? I think i have to change the port to 80, and the request to a specific domain is resolved (internally) by an internal dns server combined with round robin? At this point we have load sharing with cached http pages (very userful with static pages), but even if this works we still not have real load balancing. Lets assume i put a squid server in front of the real webserver. Dynamic webpages will still be processed over the real server btw the cache must be always refreshed. As seen at many providers, this will provide by high load servers some timing problems, the result is that you request a page and it takes 2-5 secounds before you can see anything. The overloaded squid server requests the overloaded master server, the cache needs to be rebuid and send to the client. By this way we have two machines working and the cpu´s have much to do. I want one machine per request of a client, not two even if running squid is a VERY interesting idea. I need this solution (only for interesting purposes). machine A (apache server, "master-server") machine B (apache server, "replicated directories") I would use dns round robin for load sharing if there is really no good load balancing solution (free) available (this is ok), but there is still the problem to replicate the content from A to B if anything on A changes somewhere. Running a cronjob every minute kills the harddrive someadays. I think about the coda-fs, this would be interesting, but i have never get it up and running -( -- Best regards, Boris mailto:koester@x-itec.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
