If it's a Bluecoat (or some other reverse proxy) which is load balancing
between different servers you can sometimes determine the techonology
based on the cookie used for tracking users at the app level (although
not everybody does this, some people configure reverse proxies to do
persistence by IP address or, even, no persistence).

You can use the cookie database available at:
