Virtual Web servers...

Hi,

I have a question regarding the support of virtual Web servers...
I have the following configuration:
Some virtual host Web servers on computer behind the firewall and
I would like to install squid on bastion host to work as a 'pipe'
to these Web servers, but as I understand the only option to handle
different hostnames in squid is to have a separate IPs, is it correct?
My problem is, that I can't put too many IPs on the bastion host and I
don't want to open direct access to the Web server.

Any ideas?

Thanks,
