<DL>
<DD>Set a socket option for the connection.
 <P>
 Options inform the low level networking code about intended
 usage patterns that the application will use in dealing with
 the socket connection.
 </P>
 <P>
 Calling <code>setSocketOption</code> to assign buffer sizes
 is a hint to the platform of the sizes to set the underlying 
 network I/O buffers.
 Calling <code>getSocketOption</code> can  be used to see what 
 sizes the system is using.
 The system MAY adjust the buffer sizes to account for 
 better throughput available from Maximum Transmission Unit
 (MTU) and Maximum Segment Size (MSS) data available 
 from current network information.
