Hi I wanna create a site like this:
The site needs to read the subdomain so...
the user inputs "www.fishshop.domain.com" then it must redirect to a predefined site corresponding to the fishshop subdomain but it will first check what city the person is living in with geolocation or something like that.
Then it must prompt the user with the question is this your city? If no please center correct cityname or zipcode and then it must redirect and save the city into the cookies so the user wont have to type it in again :).
