Hi,
What you are looking for is called reverse proxy. You can not do reverse
proxy on FTD. You can do SSL inspection on FTD. For this purpose, you need
to have web proxies such as WSA from Cisco. There are other vendors
performing this such as bluecoat and F5.
You can provision load balancer on apache server to terminate SSL and pass
traffic to your backend servers.
