* destination. When you use this method, the selector expressions for all subscribing clients are
* not evaluated. If you want the selector expressions to be evaluated, use a combination of the
* <code>pushMessageToClients</code> method and the <code>sendPushMessageFromPeer</code> methods.
*
* @param message The <code>Message</code> to send.
* @param sendToAllSubscribers If <code>true</code>, send this message to all clients subscribed
* to the destination of this message. If <code>false</code>, send the message only to the
