networking - Is it possible to mimic a CNAME with a http server?

Question

Disclaimer: I know it seems a bit unusual.

We work in an industry where networks are very restricted. All of our customers installations require us to deploy an on-premise server which runs in a closed network (it cannot be reached from the outside). This server is assigned a local DNS but it needs to be accessed from a web browser running within the private network, using SSL as our app is served with HTTPS.

We bypass this problem by assigning a public DNS to the local DNS, and providing the right SSL certificates on the on-premise server.

For instance:

Local DNS: server.customer.local

Public DNS: customerid.connectors.mycompany.com => CNAME to server.customer.local

The on-premise server has a certificate for *.connectors.mycompany.com, and it all works fine.

My question is whether it would be possible to do the exact same thing using a web server rather than all these DNS. The browser would target our external web server, which would "redirect" to the local server, all in a SSL context.

Any help very appreciated!
