golang 302 redirection and order of things in response

gistfile1.txt

// in order to do a redirection or any response including custom code/header/json body at the same time
// order in which they are arranged is important, one will overwrite another and you wont get proper
// response, bellow is the order which will allow you to set all 3

// any custom header goes first
w.Header().Set(
  "Location",
  "http://localhost/something/else
)

// then status code
w.WriteHeader(http.StatusFound)

// then json body
json.NewEncoder(w).Encode(resp)
