We host several secure web applications for customers.
The customer would set up a CNAME alias to map their subdomain to our subdomain
eg. customer HTTPS URL app.customersite.com/App
maps to our HTTPS URL customer.hostingserver.com/App
The customer allows us to host their SSL key & certificate which has a common name of app.customersite.com
.
However, historically, the customer also has access to the customer.hostingserver.com
URL. But if they access this URL, the SSL certificate is not trusted as the domain name does not match.
They have asked us to redirect customer.hostingvendor.com
back to app.customersite.com
somehow so both URLs would accept the SSL certificate - but surely this would set up a circular link?
Is there any way of having both these URLs working - or do we just need to convince the customer not to try and access our URL directly?
Many Thanks
