Logging APM Username and XFF Address

I'm trying to create a single log entry that is triggered by an ACCESS_POLICY_AGENT_EVENT containing a user's username (after successful logon) and their X-Forwarded-For address. This log needs to be triggered immediately after successful authentication. Here is my iRule:

when ACCESS_POLICY_AGENT_EVENT {
    log local0. "SESSION_STARTED, User=[ACCESS::session data get session.logon.last.username], IP=[HTTP::header X-Forwarded-For]"
}

However, I'm getting this as my log entry: 

Rule /Common/UserID_Logger : SESSION_STARTED, User=testuser, IP=

It seems that the http headers are not accessible from within the APM event. Any suggestions?

    Use this code

     

    when ACCESS_SESSION_STARTED {
    ACCESS::session data set session.custom [HTTP::header X-Forwarded-For]
}
when ACCESS_POLICY_COMPLETED {
    log local0. "SESSION_STARTED, User=[ACCESS::session data get session.logon.last.username], IP=[ACCESS::session data get session.custom.xff]"
}
