The user creates a TCP connection to a Web VPN server using SSL.
If the user connects to a normal web server inside the enterprise, and that server only supports HTTP and not SSL, those packets pass over the Internet unencrypted.

The web VPN client cannot connect without at least thin-client SSL software installed on the client.
