A multisite question of sorts - I have read up on the various configuration options for multisites and I have completely confused myself with my particular use case - I have a country specific primary URL and would like to serve content to specific geographically located users and therefore I cannot use subdirectories eg http://www.mysite.co.uk would end up with bizarre URLs such as http://united states.mysite.co.uk and http://australia.mysite.co.uk.
The obvious method would be to have a primary url that all other content could be tagged via location, or cck or some other internal Drupal method and then filtered by various methods or redirects via IP or user select landing pages. However I think I am boxed in with the primary domain which is up and running.
I have acquired the country specific urls eg http://www.mysite.us and http://www.mysite.au and http://www.mysite.dk etc and am assuming some symlink and apache redirect wizadry may be required. However being a novice I am again confused with what this type of set-up would looklike: for example users accessing http://www.mysite.us could be directed to http://www.mysite.co.uk (and mirrored so they see the original url (http://www.mysite.us) but would see the uk specific splash page. I'm guessing something like IP to country module could be used here to redirect the user geographically specific splash page but does that mean that http://www.mysite.us couldn't be the address of that page as it is mirroring http://www.mysite.co.uk?
I'm going to have a lie down...any help untangling this would be greatly appreciated.
