I'm creating a website for a company that has multiple countries open and different websites for each.
I want to create a landing page with the flags for each available country or a "global" site. I would like it to ask the user only the first time he accesses and remember the country he selects.
When the users clicks for example on the Colombian flag, it redirects to co.mysite.com
If the user clicks on the Mexican flag, it redirects to mx.mysite.com
The next time user visits, it remembers the choice.
