Yeah, I plan on doing that.
The manual test is done already and a harness version is coming up.

But not the way you point out ...  You're right, I must parse the reference to see if it is http or https and add the header to Rush if it is https. 

What I implemented/tested is that if the broker is started with https, the notifications are in https as well.
This was not a very good idea, I can see that now.
I should remove that approach and only add the "x-relayer-protocol: https" header to rush if the reference is with https, right?
