https redirection not working correctly

[Parzip]

could this be related to the forwarding of the address?

This is my domain registrar setting:

XXXXX.ch => web alias to subdomain.XXXXX.ch
subdomain.XXXXX.ch => A record to IP address of my server

I need this setup because my odoo-erp selects the database according to my
subdomains.
