# nginx does not auto-rotate session ticket keys: only a HUP / restart will do so and
# when a restart is performed the previous key is lost, which resets all previous
# sessions. The fix for this is to setup a manual rotation mechanism:
# http://trac.nginx.org/nginx/changeset/1356a3b9692441e163b4e78be4e9f5a46c7479e9/nginx
#
# Note that you'll have to define and rotate the keys securely by yourself. In absence
# of such infrastructure, consider turning off session tickets:
