-----BEGIN PGP SIGNED MESSAGE----- Hello Dustin, Monday, December 10, 2001, 6:41:56 AM, you wrote: > Gabriel, after rereading your message I am now definately curious > how you go about this when using multiple webservers for both IP- > and name-based virtual hosting. Normal hosting consumers we simply setup as name based, those who pay for SSL we of course give their own IP but since none of these needs load balancing (and load balancing IS a major PITA since you need bullet proof filesystem synchronization for it which I currently can't see how it should be achieved on FreeBSD), we put all on only one server. To protect us against server problems, we mirror the servers every few hours to a twin in order to have a fall back option. > Okay, so I setup my firewall to route any packets destined > for network xyz to my internal web servers.

I'd very much like to have a real time filesystem replication facility since then I could go for a setup like you want... It's easy with data that you control, since then you can store all volatile data in SQL db, but with hosting consumers, that's obviously not possible. > virtual host? I think that is what is confusing me. If it was just > named-based virtual hosting there wouldn't be an issue in my mind. You simply can't have the same IP based virtual host on two machines. The online thing that can be done there is round robin NAT but for reasons pointed out above, that's major PITA.
