Router Question

Is it possible to configure a router so it's hooked to two servers and
have it either:

1. Send requests to one server unless that one doesn't respond, and
then automatically switch over?

Is this possible for all routers currently used by the top hosting
services?

2. Send requests to two (or more) servers at once? i.e. duplicate the
requests and send to all connected servers?


I want something like this:

Yes to both, but not with low-end h/w. Contact a Cisco or HP hardware
dealer and shuffle your credit cards.

Failover. Have a look at the heartbeat package.

You want load balancing. Google for it.

One effective solution if you're serving many different hosts on the
internet is to use Round Robin DNS.

You might also try search for High Availability on the Linux Journal
website.
