HTTP Request
A message sent from a client to a server asking for data or action
An HTTP request is the fundamental communication unit of the web. It includes a method (GET, POST, etc.), a URL, headers, and optionally a body. The server processes it and returns a response with a status code and data.
Mental modelClient → server intent transmission
Where you'll encounter this
- →Frontend-backend communication
- →API development
- →Web debugging tools (DevTools, Postman)
- →Microservices architecture
What breaks when this is misunderstood
- ✕Incorrect method usage (GET vs POST)
- ✕Missing headers causing auth failures
- ✕Malformed payloads
- ✕Unexpected server responses
Signals this concept is in play
- ◆Network tab in browser DevTools
- ◆API logs showing request/response cycles
- ◆HTTP status codes (200, 404, 500)
- ◆Request payloads and headers
