All Implemented Interfaces:

Serializable, Servlet, ServletConfig, ContainerServlet

public final class HTMLHostManagerServlet
extends HostManagerServlet

Servlet that enables remote management of the virtual hosts deployed on the server. Normally, this functionality will be protected by a security constraint in the web application deployment descriptor. However, this requirement can be relaxed during testing.

The difference between the HostManagerServlet and this Servlet is that this Servlet prints out an HTML interface which makes it easier to administrate.

However if you use a software that parses the output of HostManagerServlet you won't be able to upgrade to this Servlet since the output are not in the same format as from HostManagerServlet
