Trying to understand a multisite installation. What I want to do is create a multisite environment, but do not want to be able to access it through a domain.

IE., I want to access a test drupal install by pointing my http server to: http://localhost/sites/mysite.com/
Where localhost is my local test apache server and mysite.com is my addon test site that contains its own theme+modules+settings.php folders and files.

The problem is when I use the link above I get an error. I read something about creating symbolic links on the server but am getting nowwhere.

Any ideas anyone?

Thanks,
NB
