/**
    Generates automatic Netscape nsapi_redirect configurations based on
    the Tomcat server.xml settings and the war contexts
    initialized during startup.
    <p>
    This config interceptor is enabled by inserting an NSConfig
    element in the <b>&lt;ContextManager&gt;</b> tag body inside
    the server.xml file like so:
    <pre>
    * < ContextManager ... >
    *   ...
    *   <<b>NSConfig</b> <i>options</i> />
    *   ...
    * < /ContextManager >
    </pre>
    where <i>options</i> can include any of the following attributes:
    <ul>
     <li><b>configHome</b> - default parent directory for the following paths.
                            If not set, this defaults to TOMCAT_HOME. Ignored
                            whenever any of the following paths is absolute.
                             </li>
     <li><b>objConfig</b> - path to use for writing Netscape obj.conf
                            file. If not set, defaults to
                            "conf/auto/obj.conf".</li>
     <li><b>objectName</b> - Name of the Object to execute the requests.
                             Defaults to "servlet".</li>
     <li><b>workersConfig</b> - path to workers.properties file used by 
                                nsapi_redirect. If not set, defaults to
                                "conf/jk/workers.properties".</li>
     <li><b>nsapiJk</b> - path to Netscape mod_jk plugin file.  If not set,
                        defaults to "bin/nsapi_redirect.dll" on windows,
                        "bin/nsapi_rd.nlm" on netware, and
                        "bin/nsapi_redirector.so" everywhere else.</li>
     <li><b>jkLog</b> - path to log file to be used by nsapi_redirect.</li>
     <li><b>jkDebug</b> - Loglevel setting.  May be debug, info, error, or emerg.
                          If not set, defaults to emerg.</li>
     <li><b>jkWorker</b> The desired worker.  Must be set to one of the workers
                         defined in the workers.properties file. "ajp12", "ajp13"
                         or "inprocess" are the workers found in the default
                         workers.properties file. If not specified, defaults
                         to "ajp13" if an Ajp13Interceptor is in use, otherwise
                         it defaults to "ajp12".</li>
     <li><b>forwardAll</b> - If true, forward all requests to Tomcat. This helps
                             insure that all the behavior configured in the web.xml
                             file functions correctly.  If false, let Netscape serve
                             static resources assuming it has been configured
                             to do so. The default is true.
                             Warning: When false, some configuration in
                             the web.xml may not be duplicated in Netscape.
                             Review the uriworkermap file to see what
                             configuration is actually being set in Netscape.</li>
     <li><b>noRoot</b> - If true, the root context is not mapped to
                         Tomcat.  If false and forwardAll is true, all requests
                         to the root context are mapped to Tomcat. If false and
                         forwardAll is false, only JSP and servlets requests to
                         the root context are mapped to Tomcat. When false,
                         to correctly serve Tomcat's root context you must also
                         modify the Home Directory setting in Netscape
                         to point to Tomcat's root context directory.
                         Otherwise some content, such as the root index.html,
                         will be served by Netscape before nsapi_redirect gets a chance
                         to claim the request and pass it to Tomcat.
                         The default is true.</li>
    </ul>
