HTTP status to return after trying to logout without being logged in
<p>Suppose I have a RESTful authentication endpoint:</p>

<p><code>http://example.com/api/v1/auth</code></p>

<ul>
<li>A <code>POST</code> request with email and password allows for logging in. A request gets countered with a response with HTTP 200 for correct login or 403 for incorrect.</li>
<li>A <code>DELETE</code> request allows for logging out.</li>
</ul>

<p>It's obvious that after a successfuly logout I should return HTTP 200. What HTTP response code should I return, if a user tries to logout without being logged in?</p>
