[PLUG] Firewall & Virtual Web Servers

[Casey Bralla <MailList@nerdworld.org>]

So I'm planning on virtualizing my servers, and I thought I'd also like to 
virtualize my individual web domains.   I'd appreciate advice and comments on 
my (goof-ball) plan.


I currently host several web domains on a single web server (with a single 
static IP) by utilizing Apache's virtual web server system.  So far this 
system works very well, except that it gets kinda complicated if some of the 
web sites want to do forums, or blogs, etc.  if each web page was running in 
it's own virtual machine, then this would be much easier.

Unfortunately, if each gets it's own virtual machine, how will I route traffic 
to the correct virtual machine?

Right now, my firewall forwards all port 80 traffic to a unique machine on my DMZ 
which runs Apache, and then Apache determines which web domain has been 
requested and automagically serves up the correct page(s).

I'd like to do almost the same thing, but have the firewall determine which web 
domain has been requested, and then forward it to the correct virtual machine.

Is this even possible?   Anybody have any suggestions how the firewall might 
detect which domain has been requested?

TIA!
