insert_xforwarded verification

Hi,

the best way to verify that F5 include correctly XFF is irule on F5 side or check logs in App side.

The best way is F5, you have the event:

HTTP_REQUEST_RELEASE : https://devcentral.f5.com/wiki/iRules.HTTP-REQUEST-RELEASE.ashx

An triggered when the system is about to release HTTP data on the of the connection. This event is triggered after modules process the HTTP request. So this event trigged after F5 process just before the request is sent to the backend (there is no additional process so the request is not changed anymore).

You can use my Irule:

https://devcentral.f5.com/codeshare/ultimate-irule-debug-capture-and-investigate-1183

and in irule set the var like this:

array set app_arrway_referer {
    client_dest_ip_port 1
    client_cert  0
    http_request 1
    http_request_release 1
    http_request_payload 0
    http_lb_selected 0
    http_response 0
    http_response_release 0
    http_response_payload 0
    http_time_process 0
}

So in logs (/var/log/ltm) you will see igress request and degress request (With header added by F5).

keep me in touch if you need more details.
