Answer from AI
Safe HTTP methods are those that do not alter the server's state. These include:
- GET
- HEAD
- OPTIONS
- TRACE
Idempotent methods are methods that can be called multiple times without changing the result after the first call. These include:
- GET (safe and idempotent)
- PUT
- DELETE
- HEAD
- OPTIONS
POST is not idempotent, as repeated calls can create new resources or change the server's state.
