package Acme.Serve.servlet;
/// Defines a "single" thread model for servlet execution. This empty
// interface allows servlet implementers to specify how the system should
// handle concurrent calls to the same servlet.
// <P>
// If the target servlet is flagged with this interface, the servlet
// programmer is guaranteed that no two threads will execute concurrently
// the service method of that servlet. This guarantee is ensured by
// maintaining a pool of servlet instances for each such servlet, and
// dispatching each service call to a free servlet.
// <P>
// In essence, if the servlet implements this interface, the servlet will
// be thread-safe.
// <P>
// This is taken from JavaSoft's Servlet API documentation.
