| looks up a Session object directly. |

| While a <code>SessionKey</code> allows lookup of <em>any</em> Session that might exist, this is not something in practice |
| done too often by most Shiro end-users. Instead, it is usually more convenient to acquire the currently executing |
| <code>Subject</code>'s session via the <a href="../../subject/Subject.html#getSession()"><code>Subject.getSession()</code></a> method. This interface and |

| Acquiring sessions by ID only is a suitable strategy when sessions are natively managed by Shiro directly. |

| the session ID alone is not sufficient for ServletContainer-based SessionManager implementations.</div> |
