How a request travels

Client and server, the parts of an HTTP request, methods, status codes, and why every request stands alone.

  • Briefing, about 6 minutes with quick checks · read it as a guide
  • Signal Codes (practice): Pick the status code the tower sends back for each outcome.
  • Method Lanes (practice): Put each action on the right HTTP method: GET, POST, PATCH or DELETE.
  • Tower Relay (checkpoint): Methods and status codes together, including who is logged in and who is allowed.
