The term Multi Homing refers to the practice of maintaining more than one server on one machine, differentiated by their apparent host name. It is often desirable for companies sharing a web server to have their own domains, with web servers accessible as www.company1.com and www.company2.com, without requiring the user to know any extra path information.

For an overview of Multi Homing, and how to configure it with PL, refer to the Virtual Hosting and Multi Hosting section.

This step by step example will define a virtual home for the URL http://www.ahelp.com/ to the server www.a.com and directory /departments/support/

  1. Have a domain name allocated in the DNS for the ahelp.com that points to the same IP address of the a.com that is hosting a Virtuoso server.

  2. From the Conductor UI go to Web Application Server/ Virtual Domains & Directories.

  3. To add a new host definition, enter for "Port" 80, enter for "HTTP Host" www.ahelp.com and select the "Add" button.

  4. Click for the new defined site the "Edit" link in order to define the mapping between the virtual host and the actual listening host domain names.

  7. The following URLs will then be equivalent:

    http://www.ahelp.com/
    http://www.a.com/departments/support/index.html
