Railo Resin and Virtual hosts
This is really easy in IIS ( point and click ).
Apache you have to touch some configuration files but there is alot of information out there on this.
With Resin it's also quite simple but there is far less information about this available.
I put together this walk through on the process.
And if your wondering about the performance of resin ( free edition ) Peter Bell's response should give you some confidence.
I run about 70 websites on Railo and Resin on a Win2k3 64bit server
with 8Gb of RAM and have excellent performance. Not to say it wouldn't
be better if I used the professional version.
