I haven't really found a question covering this topic and I'm sure that's because I don't know exactly how to word it.
The problem is the following: My boss has recently overtaken the Swiss branch of a small Argentinian wine company that sells wines through their website. Site looks like this so far with an English and Spanish option (as an example):
What he wants is a domain like
www.wine-argentina.ch (still needs to be bought)
which is supposed to point to the original domain but this time in German (like www.wine-argentina.com/ger). This German version is for the Swiss clients and is also supposed to include a simple form so that the Swiss clients can order wine.
I'm supposed to get into contact with their webmaster but I first wanna understand a few basics.
What is the best way to go about this? How can a domain like www.wine-argentina.ch be used in WP so that it points to some other domain like "www.wine-argentina.com/ger"?
