Insert x-forwarded-proto and x-forwarded-port - Is this the correct way to do it?

Hi,

In your irule, you add only one header, X-Forwarded-Proto or X-Forwarded-Port (else if statement).

Evaluate port 443 is not the best way to test if protocol is HTTPS. Evaluate SSL::mode instead.

Try the following irule.

when HTTP_REQUEST {
if { [SSL::mode] == 1 } {
    if {!( [HTTP::header "X-Forwarded-Proto"] eq "https") }{
        HTTP::header insert X-Forwarded-Proto "https"
    }
    if { !( [HTTP::header exists "X-Forwarded-Port"]) }{
        HTTP::header insert X-Forwarded-Port [TCP::local_port]
    }
}
