$ go env

What did you do?

Overwrote the ModifyResponse method in Reversproxy and set the status of Response to a custom value. In addition to that changed the status code of the response as well

resp.StatusCode = 201
resp.Status = "Custom object created"

What did you expect to see?

Expected to see the status-code as well as the status message to change in the final response

What did you see instead?

Only the status code was changed, but the status message was never changed.
