  <title>Sessions support</title>
- <para>...</para>
+ <para>Memcached provides a custom session handler that can be used to store
+  user sessions in memcache. A completely separate memcached instance is used
+  for that internally, so you can a different server pool if necessary. The
+  session keys are stored under the prefix
+  <literal>memc.sess.lock_key.</literal>, so be aware of this if you use the
+  same server pool for sessions and generic caching.</para>
