How to send pushpin instance details while making a call to backend service?

I want to from which pushpin istance like, podname, I received the request.

Hi, one way to do this would be to use your Pushpin instance’s routes configuration.

There’s a route condition parameter header that can set arbitrary hard-coded headers on proxied requests.

If your routes file could be templatized with the pod name then you could use this.

I am passing headers like below

but I am not receiving this Header in Backend service

I don’t think HTTP headers are supposed to have underscores. Maybe try a different name?
