You are hosting multiple secure web applications behind a single public IP address on FortiWeb.

When multiple HTTPS applications share one public IP address, the client begins the TLS connection and includes the requested hostname in the SNI field. FortiWeb uses SNI-based certificate selection to choose the appropriate certificate for that hostname. After presenting the correct certificate and completing the TLS handshake, FortiWeb decrypts the HTTPS session so it can inspect HTTP content. Content inspection then evaluates the host header and URL path, which are needed for application-aware routing decisions. Finally, intelligent traffic routing forwards the request to the correct back-end server or server pool. The sequence matters: FortiWeb cannot inspect the host and URL path or route by content until the HTTPS session is terminated and decrypted.
