The servers listen for the web site – using host headers.
So when I want to go to the default web page on the server – I type “images.dev.testme.com”. This will bring me to the default page for this web site. This web server has 12 different web sites listening on the same ip address. In order to distingue between the different sites, they are using host headers.
Now they want to put “images.dev.testme.com” on two servers - and load balance between them.
So the customer wants to front end this site with a bigip. So when the customer types the “VS”’s IP address – they will be load balanced to the web server instances on the server.
So the clients do not - and will not know the host name. Just the VS's ip address.
