    # nginx does not auto-rotate session ticket keys: only a HUP / restart will do so and

    # sessions. The fix for this is to setup a manual rotation mechanism:

    # Note that you'll have to define and rotate the keys securely by yourself. In absence
    # of such infrastructure, consider turning off session tickets:
