Multiple Instances under 1 domain

["Buddy" <webforumsuser@xxxxxxxxxxxxxx>]

Hello. Is it possible to create multiple instances under the same domain? For 
example, I would like to have everything under inetpub/wwwroot/mysite to run 
when I go to www.mysite.com/. But I'd like everything under 
inetpub/wwwroot/mysite/admin to run as a separate instance (admin) at 
www.mysite.com/admin.

 The problem is, I can't seem to connect the extra instance to the same IIS web 
site using wsconfig. I was under the impression that I could use the 
application.xml/context-root setting of the admin instance to cause JRun to use 
that instance. Am I mistaken?

 I can easily create an additional IIS web site under the domain 
admin.mysite.com and connect the admin instance to that, but the boss wants to 
use a single domain. Any clues?

 Thanks a bunch for any help you can give me.
