gpt: A. A certificate should be installed on the server.
B. Incoming port 80 traffic at the firewall should be forwarded to port 443 on the server.
Explanation:
Install a certificate on the server (A): Even though the server cannot serve HTTPS traffic directly, you can install a certificate on the server to handle the encryption once the traffic reaches it.
Forward port 80 traffic to port 443 at the firewall (B): Since the server cannot handle HTTPS traffic directly, the firewall can be configured to forward incoming port 80 (HTTP) traffic to port 443 (HTTPS) on the server, where the encryption can be applied.
These measures allow encryption to be implemented at the firewall, even if the web server itself cannot handle HTTPS traffic directly.
