As wel as comments inline, I've also pasted in the "tree walking"
rules from settings.php at the end.

Try actually putting in an myserver.mysite entry, rather than default
(you should be able to just rename default). It seems to be walking up
the path and "Defaulting" to default when it shouldn't be. In general,
I don't use default unless I am only running one site OR I actually
will symlink myserver --> default....just so it's clear what I
*expect* the default to be.

Also, set base_url's for both in settings.php. That's sort of a
general troubleshooting tip if you're having difficulties getting the
proper domain to resolve.

There should be no /var/www/mysite/foo at all. If this does not work,
it's a bug.

I'm being anal about this, because documenting this the wrong way
is...well, wrong.

It is complicated by the fact that a combination of shared hosting DNS
and webserver set ups can make this look completely..well, different,
and again, really hard to troubleshoot and get working correctly.

So, we can actually only document very specific combinations if
hosting has things set up strangely -- "If your host uses cpanel, and
subdomains are created as directories, then you need to symlink".

 *  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
