2.4. SSI

编辑 context.xml 文件，增加 privileged="true 属性

		
# vim /srv/apache-tomcat/conf/context.xml

<Context privileged="true">

    <!-- Default set of monitored resources -->
    <WatchedResource>WEB-INF/web.xml</WatchedResource>

    <!-- Uncomment this to disable session persistence across Tomcat restarts -->
    <!--
    <Manager pathname="" />
    -->

    <!-- Uncomment this to enable Comet connection tacking (provides events
         on session expiration as well as webapp lifecycle) -->
    <!--
    <Valve className="org.apache.catalina.valves.CometConnectionManagerValve" />
    -->

</Context>
		
		

编辑 web.xml 文件，取消下面的注释

		
# vim /srv/apache-tomcat/conf/web.xml	
	
    <servlet>
        <servlet-name>ssi</servlet-name>
        <servlet-class>
          org.apache.catalina.ssi.SSIServlet
        </servlet-class>
        <init-param>
          <param-name>buffered</param-name>
          <param-value>1</param-value>
        </init-param>
        <init-param>
          <param-name>debug</param-name>
          <param-value>0</param-value>
        </init-param>
        <init-param>
          <param-name>expires</param-name>
          <param-value>666</param-value>
        </init-param>
        <init-param>
          <param-name>isVirtualWebappRelative</param-name>
          <param-value>false</param-value>
        </init-param>
        <load-on-startup>4</load-on-startup>
    </servlet>
		
		

配置需要SSI处理的文件

		
# vim  /srv/apache-tomcat/webapps/ROOT/WEB-INF/web.xml

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                      http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
  version="3.0"
  metadata-complete="true">

  <display-name>Welcome to Tomcat</display-name>
  <description>
     Welcome to Tomcat
  </description>


	<servlet-mapping>  
        <servlet-name>ssi</servlet-name>  
        <url-pattern>*.shtml</url-pattern>  
        <url-pattern>*.html</url-pattern>  
	</servlet-mapping>  


</web-app>
		
		

重新启动Tomcat
