After a long wait and intermittent efforts, I now have multiple websites running on a single drupal-4.6.2 install. Now that I have done it, it was quite simple. In the first test, I set a second domain to alias the first, in toher words the exact same website was reached by both the original domain name and also the new one. Then I created a folder in my /sites folder called newdomain.tld and added a settings.php file that calls a different database. It can be viewed for now at cafeamerican.info. What will I ever do after those free .info domains I use for testing finally expire?

The second test was slightly more difficult. The example in the settings.php file is as follows:

* For example, for a fictitious site installed at
 * http://www.drupal.org/mysite/test/, the 'settings.php'
 * is searched in the following directories:
 *
 *  1. sites/www.drupal.org.mysite.test
 *  2. sites/drupal.org.mysite.test
 *  3. sites/org.mysite.test
 *
 *  4. sites/www.drupal.org.mysite
 *  5. sites/drupal.org.mysite
 *  6. sites/org.mysite
 *
 *  7. sites/www.drupal.org
 *  8. sites/drupal.org
 *  9. sites/org
 *
 * 10. sites/default

but when I tried doing it this way I only got a File Not Found. Having nothing to lose at this point, tried it with a subfolder, creating a folder in my sites folder more like this:

     sites/www.mysite.test.drupal.org

This was the thing to do, and you can view the results at: yoursite.cafeamerican.com
Note that I did not create a sub domain in my control panel.

Time to celebrate.
