package javax.servlet;

/**
 * Ensures that servlets handle
 * only one request at a time. This interface has no methods.
 *
 * <p>If a servlet implements this interface, you are guaranteed
 * that no two threads will execute concurrently in the
 * servlet's <code>service 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>Note that SingleThreadModel does not solve all thread safety
 * issues.  For example, session attributes and static variables can
 * still be accessed by multiple requests on multiple threads
 * at the same time, even when SingleThreadModel servlets are used.
 * It is recommended that a developer take other means to resolve
 * those issues instead of implementing this interface, such as
 * avoiding the usage of an instance variable or synchronizing
 * the block of the code accessing those resources.
 * This interface is deprecated in Servlet API version 2.4.
 *
 *
 * @author	Various
 *
 * @deprecated	As of Java Servlet API 2.4, with no direct
 *	replacement.
