<DL>
<DD>Attempts to get a new socket connection to the given host within the
 given time limit.
 <p>
 This method employs several techniques to circumvent the limitations
 of older JREs that do not support connect timeout. When running in
 JRE 1.4 or above reflection is used to call
 Socket#connect(SocketAddress endpoint, int timeout) method. When
 executing in older JREs a controller thread is executed. The
 controller thread attempts to create a new socket within the given
 limit of time. If socket constructor does not return until the
 timeout expires, the controller terminates and throws an
 <CODE>ConnectTimeoutException</CODE>
