Learn to apply same-site cookies, state tokens, origin checks, and replay resistance in a secure engineering review room while explaining the invariant, safety constraints, and hidden edge cases.
- Demonstrates same-site cookies, state tokens, origin checks, and replay resistance
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids unsafe dynamic execution
