All - Have a problem which I am certain many of you have already encountered. With most web servers, you can create specific web server instances that listen to virtual network interfaces on the server (virtual IP addresses). For example, I can have multiple httpd instances, with httpd1 listening to 192.168.1.101 and httpd2 listening to 192.168.1.102 on a box where the physical IP address is 192.168.1.100. This is configurable within the web server. I want to be able to have Zope listen to a specific network interface, i.e. - a virtual IP address that has been created on the server. This will allow me to have multiple Zope sites running on the same machine. How can this be accomplished? Any/all suggestions are greatly appreciated. Thanks, -Brian
