HTTPS

HTTPS is a secured and encrypted version of the HTTP protocol. The
client and the web server set up an encrypted session over TCP port 443.
Because this session is encrypted on both ends, the proxy cannot examine
packet contents; therefore, this icon enables a packet-filter service, not a
proxy.
The HTTPS service is needed only if you are hosting an HTTPS server, or
if you do not have an Outgoing, Filtered-HTTP , Proxy or Proxied HTTP
icon in your configuration.
