I'm trying to configure a load balance environment for Umbraco.  I've read the documentation and watched the 10 min video on setting one up.  In the umbracoSettings.config file for the distributed call, the video added the following fields:

<server>admin.umbraco.local</server>
<server>site1.umbraco.local</server>
<server>site2.umbraco.local</server>
<server>site3.umbraco.local</server>

Now - these were all hosted on his localhost.  I want to do this for 3 separate servers.  I'm using Cisco CSS load balancer that will have a virtual IP (VIP) and have each server to the VIP.  So based on the public DNS, each server will have a matching host header on each server.  For the config settings above, I obviously can't use a host header, can I use the FQDN of the server?  Something like Webserver01.domain.com, Webserver02.domain.com, Webserver03.domain.com?  Does the <server> setting match with the host header on the web server and if so - does that mean I need to create a second unique host header?

I found the video to be underwhelming and did not do a good job of explaining his examples.
