I'm not 100% sure, but since the F5 is inserting the header to send to the server I would not expect it to be there when HTTP_REQUEST is being processed. HTTP_REQUEST should have what is being sent by the client and unless the client is sending that header it should not be there.

It is present in 11.6. What version are you running? Try this:
when HTTP_REQUEST { foreach x [HTTP::header names] { log local0. "$x = [HTTP::header $x]" } }Do you see the XFF header in the log?
