I have google analytics installed for my own domain,
http://mydomain.com. Will a user that enters
http://www.mydomain.com be counted by the analytics script too?
To me it seems logical that it would, since it is so common to have the naked domain address be the same site as the www-prefixed one, but the analytics documentation doesn't state it explicitly.
For the sake of completeness, there is a way to tell Google Analytics to share session information between to different hosts with the
pageTracker._setDomainName function, but that is not the right answer for the current situation.
Yes, that has been my experience.
