  <!-- ======================== Introduction ============================== -->

  <!-- This document defines default values for *all* web applications      -->

  <!-- loaded into this instance of Tomcat.  As each application is         -->

  <!-- deployed, this file is processed, followed by the                    -->

  <!-- ""/WEB-INF/web.xml"" deployment descriptor from your own               -->

  <!-- applications.                                                        -->

  <!--                                                                      -->

  <!-- WARNING:  Do not configure application-specific resources here!      -->

  <!-- They should go in the ""/WEB-INF/web.xml"" file in your application.   -->

  <!-- ================== Built In Servlet Definitions ==================== -->

​

​

  <!-- The default servlet for all web applications, that serves static     -->

  <!-- resources.  It processes all requests that are not mapped to other   -->

  <!-- servlets with servlet mappings (defined either here or in your own   -->

  <!-- web.xml file).  This servlet supports the following initialization   -->

  <!-- parameters (default values are in square brackets):                  -->

​

    <servlet>
