<ul>
<li>Instructs the session storage backend to create/update/delete/retrieve the state attached to

<p>You should not regret adding <code>actix-session</code> to your dependencies and going to production using
the default configuration. That is why, when in doubt, we opt to use the most secure option for
each configuration parameter.</p>
<p>We expose knobs to change the default to suit your needs—i.e., if you know what you are doing,
we will not stop you. But being a subject-matter expert should not be a requirement to deploy
reasonably secure implementation of sessions.</p>
