The client requests go with a cookie request header and deserve request

• Basic concepts

  • Request: Client Access server
  • Response: The server response to client
  • sample graph

• With a special request headers and cookie worth client requests way

  • Use: http.NewRequest, Do () combination. And in the creation of the request, bring value and other cookie request header
  • Reference Code
