Apache question

[Paul Guba]

Have Apache running on YDL 2.1.  I have a virtual host directive sever 
booth of my domains.  I can load booth domains from outside my LAN 
fine.  While within my LAN I can only connect to one of the domains.  
This is of course the first in the virtual host directive.  Now I think 
I may need a host alias but not sure the documentation on this is not to 
clear to me.  Presently if I type in 	http://hostname in my browser I 
get the first domain.  I get nothing if I put in the domain names.
