I would like to forward http*://*.pfeiffer-china.com/* to http*://www.gebr-pfeiffer.com.
The domain should change to gebr-pfeiffer so the SSL cert will match.
Do you want to redirect pfeiffer-china.com to gebr-pfeiffer.com? Or do you want to keep pfeiffer-china.com in the URL but display the contents of gebr-pfeiffer.com?
You’ll need to add a proxied DNS record on pfeiffer-china.com for Dynamic Redirects to work. I suggest you create the following DNS records (both proxied):
pfeiffer-china.com IN AAAA 100::
www.pfeiffer-china.com IN CNAME pfeiffer-china.com
Redirects from pfeiffer-china.com should then work. If you also want to redirect www.pfeiffer-china.com to www.gebr-pfeiffer.com, you will have to create another Dynamic Redirect rule.
