X-Authenticated-User chaining

You can pass authentication details from your Blue Coat proxy to send X-Forwarded-For and X-Authenticated-User headers to the cloud proxy either by manually editing a policy text file, or defining the policy in Blue Coat Visual Policy Manager.

X-Forwarded-For	Contains the client IP address
X-Authenticated-User	When Blue Coat authentication is turned on, this header will be populated with the user domain and username (domain\user).

With this setup, end users can be authenticated transparently by the cloud proxy, removing an authentication step and improving performance.

Note that for Blue Coat to service HTTPS requests properly with the following setup, you must have a Blue Coat SSL license and hardware card.
