DNS can only control what IP address the client connects to. It doesn't 
have any effect on the "Host:" header that is sent in the HTTP request, 
and that's what a webserver uses to identify the target site, in a 
named-based virtual hosting context.

I think you want to use a proxy with URL-rewriting capability. SQUID 
seems to be capable of this.

Possibly some browser add-on might have a URL-rewriting capability too, 
haven't looked into that.
