CNAME Listing in BIND for Domain Outside of My Control

[Dawn Connelly]

The problem is with host headers. The destination webserver is inspecting
the URL that people are trying to access and then matching that to a
specific webpage. If the URL that people are putting into the browser is not
configured on the webserver, it doesn't understand what page you are trying
to get to. The problem isn't the fact that it's CNAME'ing to a CNAME...it's
a webserver issue.
