Servlet that enables remote management of the web applications deployed
within the same virtual host as this web application is.  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 ManagerServlet 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
ManagerServlet you won't be able to upgrade
to this Servlet since the output are not in the
same format ar from ManagerServlet
