Re: How find Ip Address of clients who r currentlt: msg#00142 java.jetty.support

The session manager is configurable and you can call setSessionManager
on the ServletHandler (which you can get from the HttpContext or
WebApplicationContext).

I'll add the following method to AbstractSessionManager:

public Map getSessionMap()
{
return Collections.unmodifiableMap(_sessions);
}

This will allow you to query a SessionManager for it's active session.

I'll also make some private attributes public so that you can do
fancier things with the session manager if you want.
