title: Publishing multiple sites on a single instance of umbraco
body: <p>I am looking to setup a parallel site to one already that already uses umbraco for its content management system.  The new site would share admins, templates, macros, and media resources, but not any content.  If I setup multiple host headers pointing to the same directory with an umbraco install, how can I switch the top node (home vs home2) of the site based on which url is being accessed?</p>
