What you will learn

  • Review identity and stateful failure boundaries explicitly.
  • Maintain correct variants and evidence-bound change decisions.

  1. Forwarded client addresses and proxy trust

    Distinguish the connection peer from a claimed original client before using addresses in logs or authorization.

    Start learning

  2. Authentication, authorization composition, and merging

    Separate identity proof from permission and review the effective Boolean and section contract.

    Start learning

  3. Balancer members, health, and failure semantics

    Choose routing and recovery contracts without assuming that retrying another backend reverses a failed business operation.

    Start learning

  4. HTTP cache correctness and private representations

    Review freshness, validation, representation keys, and access boundaries before enabling shared reuse.

    Start learning

  5. Latency evidence and bounded diagnosis

    Connect request timing, worker state, backend evidence, and user impact without running probes or load.

    Start learning

  6. Reviewed configuration changes and compatible recovery

    Version effective inputs and validate behavior without equating parser success or graceful lifecycle with user success.
