/**
 * {@link FactoryBean} for Hessian proxies. Exposes the proxied service
 * for use as a bean reference, using the specified service interface.
 *
 * <p>Hessian is a slim, binary RPC protocol.
 * For information on Hessian, see the
 * <a href="http://hessian.caucho.com">Hessian website</a>
 * <b>Note: As of Spring 4.0, this proxy factory requires Hessian 4.0 or above.</b>
 *
 * <p>The service URL must be an HTTP URL exposing a Hessian service.
 * For details, see the {@link HessianClientInterceptor} javadoc.
