The Logic

Basically this module tests to see

• If you have a writable session.
• If you have already been redirected.
• Which country you are in.
• If the URL you requested already has a country code.
• Which languages are provided for on the site.

This project is inspired by this tutorial.

What this module do ?

1. Detect the user location
2. Browse country database for checking out the user language
3. Redirect to the right language if it's enabled by i18n and the user are not already redirected to it
4. If the user was alreday redirected and he pick another language he will be not redirected another time
