multiple SSL key's on one IP several Vhosts...

Hi - 

I'm facing a similar situation, and planned to resolve it running
multiple apache-ssl invocations that specify their own IP/domain/etc

Then this was presented to me, suggesting that one apache-ssl invocation
could use IP based vhosting with multiple certs for the same effect but
less resources.

It's from May 1999, but looks possible since different certs are bing
used for different IP/domains; however I have the feeling apache will
choke on the second ssl IP. Has anyone used a similar setup or have
from the following thread:
