public class RequestAttributeMutexListener
extends Object
implements ServletRequestListener

Servlet 2.3 HttpSessionListener that automatically exposes the request attribute mutex when an ServletRequest gets created. To be registered as a listener in web.xml.

The request attribute mutex is guaranteed to be the same object during the entire lifetime of the request, available under the key defined by the REQUEST_MUTEX_ATTRIBUTE constant. It serves as a safe reference to synchronize on for locking on the current request attributes.
