We have an installation with 4 websites, each is meant for different market / language. We also have 4 landing pages in different domains and from those we need to be able to link customers directly to the correct websites in Magento.
None of the 4 websites in Magento is "main" website. So I was thinking if we could have each presented in subfolder like www.example.com/fr and www.example.com/de Could there be a language selection page/screen in the main www.example.com url where customer could select the correct website manually by clicking big country flags? How should I set this up? Do I need fifth website set up that only has the home page set up with those flags?
I'm also thinking automatic IP based redirection, but that might be a bit difficult if we want to link directly to the correct website.
