44   * This class provides a HTTP utility for the <code>com.liferay.portlet.workflow.service.WorkflowTaskServiceUtil</code>
45   * service utility. The static methods of this class calls the same methods of the
46   * service utility. However, the signatures are different because it requires an
47   * additional <code>com.liferay.portal.security.auth.HttpPrincipal</code> parameter.
48   * </p>
49   *
50   * <p>
51   * The benefits of using the HTTP utility is that it is fast and allows for tunneling
52   * without the cost of serializing to text. The drawback is that it only works with
53   * Java.
54   * </p>
55   *
56   * <p>
57   * Set the property <code>tunnel.servlet.hosts.allowed</code> in portal.properties
58   * to configure security.
59   * </p>
60   *
61   * <p>
62   * The HTTP utility is only generated for remote services.
