HTTP X-Forwarded-For header support in IDP

The log-xff-header option records the x-forward-for header (xff-header) information. During the traffic flow, IDP saves the source IP addresses (IPv4 or IPv6) from the contexts for HTTP and STMP traffics and displays in attack logs. 

The xff-header is not processed unless it's enabled through sensor-configuration. 

• To enable the xff-header, use the [set security idp sensor-configuration global log-xff-header] command. 
• To disable the xff-header, use the [delete security idp sensor-configuration global log-xff-header] command.
