Redundant or Load Balanced Apache Proxies

Hi,

I'm wondering whether I can load balance (make redundant) my Apache
proxies.

What I mean is something like this in Apache conf:

ProxyRemote * http://foo-0.bar.dom:8080
ProxyRemote * http://foo-1.bar.com:8080
ProxyRemote * http://foo-2.bar.com:8080

Thus, when a request comes in, Apache will either randomly pick one of
the three, or rotate through the list.

That way I can avoid having a single point of failure proxy.

Alternatively, does Apache do DNS lookups each time it wants to
connect to a proxy, because that would let me assign multiple IPs to
one FQDN, that Apache will cycle through, as DNS will rotate through
the addresses it knows.

Thanks,
JD
