This property determines whether the communication between the client and WebSocket server should be over a dedicated Gateway
conection or over a pool of shared connections.  It may be set to one of the following:

<li><b>SharedConnection=0</b> - The WebSocket server communicates with the client via a dedicated Gateway connection. In this mode of operation the hosting connection is effectively 'private' to the application session.</li>
<li><b>SharedConnection=1</b> - The WebSocket server communicates asynchronously with the client via a fixed number of shared Gateway connections.</li>
