Origin header not propagated and not settable

[adamreisnz]

I've been using node-http-proxy via http-proxy-middleware, but found that the origin header is not being propagated to the target server, nor was I able to set it via the proxyReq interface.

Is there a way to ensure the proxy will pass on the origin header in the request or avoid it from being removed/stripped?

It seems it was user error, I was using proxyRes instead of proxyReq to set the header, but proxyRes is the actual response from the target.
