The device can collect a client’s true IP address before a forwarding proxy IP
address overwrites it. X-Forwarded-For and TrueClient-IP technologies identify a request’s
source IP address without having to refer to proxy logs or Web server logs. When possible,
the
device will detect this and provide the original Client IP address in the Inspection
Events.
You can also configure the device to display HTTP context information, including
the requester's URI, method, and hostname. When possible, the devices will detect
this and
provide the HTTP hostname, URI, and method in the Inspection event.
