Hi All,

I would like to send a (public) user of my BB app/website to the correct landingpage; 

My app has multiple hostnames;

• https://www.example.com
• https://hostname1.example.com
• https://hostname2.example.com
• https://www.example.eu
• https://hostname1.example.eu

How can I fetch the initial hostname and always redirect the (public) user to the correct landingpage?
This hostname needs to be handled continiously throughout the user session, whenever the user will browse through the app/website.
