I'm looking to find out if it's possible to share a single IP address and port for multiple websites by using some type of traffic inspector/director.
Basically I want to host multiple web sites using a single IP, but I have a requirement to have the web sites on physically seperated servers.
Yes, I am fully aware of Host name headers and have been using them for years, but all of the websites must co-exist on a single physical server and I can not do this here.
I'm wondering if there is software or hardware which could recieve the incoming traffic, inspect the hostname header information and then direct it to the appropriate server?
I would think some form of network load balancer might do this, but havent found one yet.
Is there any technical reasons why something like this couldn't exist?
