     Creates a connection object that will handle the given request and response.

Method Summary
 voiddisposeUserInstance()
     Disposes of the UserInstance associated with this Connection.
public  OutputStreamgetOutputStream()
     Returns the OutputStream object that may be used to generate a response.
public  ObjectgetProperty(String key)
     Returns a property from the Connection-persistent property map.
public  HttpServletRequestgetRequest()
     Returns the HttpServletRequest wrapped by this Connection.
public  HttpServletResponsegetResponse()
     Returns the HttpServletResponse wrapped by this Connection.
public  WebRenderServletgetServlet()
     Returns the WebRenderServlet wrapped by this Connection.
public  UserInstancegetUserInstance()
     Returns the UserInstance associated with this connection.
public  PrintWritergetWriter()
