    Hi

    Have you tried storing the xxf header as an APM variable right at the start when then policy first fires....?

    when HTTP_REQUEST {
if {[HTTP::header exists X-Forwarded-For]}{
set xff [HTTP::header values X-Forwarded-For]
}
}
 
when ACCESS_SESSION_STARTED {
if {[info exists xff]}{
ACCESS::session data set session.custom.xff $xff
}
}

    If the value is saved as an APM variable then you should be able to manipulate it (or take action if it is empty) further on in the APM policy

HTTP headers are available in ACCESS_SESSION_STARTED event... no need to work in multiple events.
