/**
* Servlet that enables remote management of the web applications installed 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.
* 
* This servlet examines the value returned by <code>getPathInfo()</code> and related query parameters to determine what
* action is being requested. The following actions and parameters (starting after the servlet path) are supported:
* <ul>
* <li>/deploy?config={config-url} - Install and start a new web application, based on the contents of the
* context configuration file found at the specified URL. The <code>docBase</code> attribute of the context
* configuration file is used to locate the actual WAR or directory containing the application.</li>
* <li>/deploy?config={config-url}&war={war-url}/ - Install and start a new web application, based on the
* contents of the context configuration file found at <code>{config-url}</code>, overriding the <code>docBase</code>
* attribute with the contents of the web application archive found at <code>{war-url}</code>.</li>
* <li>/deploy?path=/xxx&war={war-url} - Install and start a new web application attached to context path
* <code>/xxx</code>, based on the contents of the web application archive found at the specified URL.</li>
* <li>/list - List the context paths of all currently installed web applications for this virtual host. Each
* context will be listed with the following format <code>path:status:sessions</code>. Where path is the context path.
* Status is either running or stopped. Sessions is the number of active Sessions.</li>
* <li>/reload?path=/xxx - Reload the Java classes and resources for the application at the specified path.</li>
* <li>/resources?type=xxxx - Enumerate the available global JNDI resources, optionally limited to those of the
* specified type (fully qualified Java class name), if available.</li>
* <li>/serverinfo - Display system OS and JVM properties.
* <li>/sessions - Deprecated. Use expire.
* <li>/expire?path=/xxx - List session idle time information about the web application attached to context path
* <code>/xxx</code> for this virtual host.</li>
* <li>/expire?path=/xxx&idle=mm - Expire sessions for the context path <code>/xxx</code> which were idle for
* at least mm minutes.</li>
* <li>/sslConnectorCiphers - Display diagnostic info on SSL/TLS ciphers that are currently configured for each
* connector.
* <li>/start?path=/xxx - Start the web application attached to context path <code>/xxx</code> for this virtual
* host.</li>
* <li>/stop?path=/xxx - Stop the web application attached to context path <code>/xxx</code> for this virtual
* host.</li>
* <li>/threaddump - Write a JVM thread dump.</li>
* <li>/undeploy?path=/xxx - Shutdown and remove the web application attached to context path <code>/xxx</code>
* for this virtual host, and remove the underlying WAR file or document base directory. (NOTE - This is only
* allowed if the WAR file or document base is stored in the <code>appBase</code> directory of this host, typically as a
* result of being placed there via the <code>/deploy</code> command.</li>
* <li>/vminfo - Write some VM info.</li>
* <li>/save - Save the current server configuration to server.xml</li>
* <li>/save?path=/xxx - Save the context configuration for the web application deployed with path
* <code>/xxx</code> to an appropriately named context.xml file in the <code>xmlBase</code> for the associated
* Host.</li>
* </ul>
* 
* Use <code>path=/</code> for the ROOT context.
* 
* 
* The syntax of the URL for a web application archive must conform to one of the following patterns to be successfully
* deployed:
* 
* <ul>
* <li>file:/absolute/path/to/a/directory - You can specify the absolute path of a directory that contains the
* unpacked version of a web application. This directory will be attached to the context path you specify without any
* changes.</li>
* </ul>
* 
* NOTE - Attempting to reload or remove the application containing this servlet itself will not succeed.
* Therefore, this servlet should generally be deployed as a separate web application within the virtual host to be
* managed.
* 
* The following servlet initialization parameters are recognized:
* <ul>
* <li>debug - The debugging detail level that controls the amount of information that is logged by this servlet.
* Default is zero.
* </ul>
