    A handle which represents connection between two end-points regardless of
    transport types.
  </p>
  <p>
    <a href="../../../../../org/apache/mina/core/session/IoSession.html" title="interface in org.apache.mina.core.session"><code>IoSession</code></a> provides user-defined attributes.  User-defined attributes
    are application-specific data which are associated with a session.
    It often contains objects that represents the state of a higher-level protocol
    and becomes a way to exchange data between filters and handlers.
  </p>
  <h3>Adjusting Transport Type Specific Properties</h3>
  <p>
    You can simply downcast the session to an appropriate subclass.
  </p>
  <h3>Thread Safety</h3>
  <p>
    <a href="../../../../../org/apache/mina/core/session/IoSession.html" title="interface in org.apache.mina.core.session"><code>IoSession</code></a> is thread-safe.  But please note that performing
    more than one <a href="../../../../../org/apache/mina/core/session/IoSession.html#write-java.lang.Object-"><code>write(Object)</code></a> calls at the same time will
    cause the <a href="../../../../../org/apache/mina/core/filterchain/IoFilter.html#filterWrite-org.apache.mina.core.filterchain.IoFilter.NextFilter-org.apache.mina.core.session.IoSession-org.apache.mina.core.write.WriteRequest-"><code>IoFilter.filterWrite(IoFilter.NextFilter,IoSession,WriteRequest)</code></a>
    to be executed simultaneously, and therefore you have to make sure the
    <a href="../../../../../org/apache/mina/core/filterchain/IoFilter.html" title="interface in org.apache.mina.core.filterchain"><code>IoFilter</code></a> implementations you're using are thread-safe, too.
  </p>
  <h3>Equality of Sessions</h3>
  TODO : The getId() method is totally wrong. We can't base
  a method which is designed to create a unique ID on the hashCode method.
  <a href="https://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Object.html?is-external=true#equals-java.lang.Object-" title="class or interface in java.lang"><code>Object.equals(Object)</code></a> and <a href="https://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Object.html?is-external=true#hashCode--" title="class or interface in java.lang"><code>Object.hashCode()</code></a> shall not be overriden

  When you implement a client that receives a broadcast message from a server
