<DL>
<DD>Invoked from an I/O processor thread when a new connection has been created.
 Because this method is supposed to be called from the same thread that
 handles I/O of multiple sessions, please implement this method to perform
 tasks that consumes minimal amount of time such as socket parameter
 and user-defined session attribute initialization.

 <A HREF="../../../../org/apache/mina/common/IoHandler.html#sessionCreated(org.apache.mina.common.IoSession)"><CODE>sessionCreated(IoSession)</CODE></A>.  The biggest difference from
 <A HREF="../../../../org/apache/mina/common/IoHandler.html#sessionCreated(org.apache.mina.common.IoSession)"><CODE>sessionCreated(IoSession)</CODE></A> is that it's invoked from other thread
 than an I/O processor thread once thread modesl is configured properly.
