<P>
Ensures that servlets handle
 only one request at a time. This interface has no methods.

 <p>If a servlet implements this interface, you are <i>guaranteed</i>
 that no two threads will execute concurrently in the
 servlet's <code>service</code> method. The servlet container
 can make this guarantee by synchronizing access to a single
 instance of the servlet, or by maintaining a pool of servlet
 instances and dispatching each new request to a free servlet.

 <p>This interface does not prevent
 synchronization problems that result from servlets accessing shared
 resources such as static class variables or classes outside
 the scope of the servlet.
