🔗HTTP Responses

If you’ve a http.ResponseWriter object and using it to directly write the response to the connection, the order in which you write different parts of response is very important:

// First write headers.
wr.Header().Set("Content-Type", "text/plain; version=0.0.4")
// Then set the status code. And yes, this is the function name for setting status code!
// Then finally write the response body.
wr.Write([]byte("hello world"))
