Content-Type— the media type of the response body (e.g.text/html; charset=utf-8).Content-Length— the byte length of the response body.Location— the target URL for a redirect (3XX).Set-Cookie— the cookie the server attaches to the client for future requests.Date— the server’s timestamp for the response.Connection— connection control, e.g.close.X-Powered-By— a non-standard banner advertising the server framework; servers should withhold it to reduce information disclosure.
