Serving outside with internal domain

Hi,

Our domain (interaccess.nl) is used internally, except for our
web-server (www.interaccess.nl) which is located at an ISP here in
Holland.

Is it possible to configure squid to server this web-server, e.g. how do
I convince squid that the web-server in not located internal, but this
one should be looked up outside our domain.

Regards,

Richard.
