We have is two Magento site views, the /row/ view using a sub-directory. http://www.bowersgroup.co.uk http://www.bowersgroup.co.uk/row
We have set up a redirection so that all countries point to the /row/ store.
The UK points to the main URL.
But, if a UK user visits the /row/ store, they can see it, instead of being redirected to the main domain.
Likewise, if another country visits the main domain, they are not redirected to the /row/ store.
