Trouble with Basic Reverse Proxy to an IIS machine

Question

Hi All,
          I am a bit new at this, so bear with me. I am attempting to use Weblogic 8.1 SP3 as a Reverse Proxy to an IIS server. I have configured the HttpProxyServlet and it is the default servlet in my server.
          The kicker here is that it works to google.com or cnn.com, but it fails with a 404 to my internal IIS server. Could IIS be doing something to prevent this?
          My web.xml looks like this:
          <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
          <web-app>
          <display-name>HttpProxyServlet</display-name>
          <description>HttpProxyServlet</description>
          <servlet>
          <servlet-name>HttpProxyServlet</servlet-name>
          <display-name>HttpProxyServlet</display-name>
          <servlet-class>weblogic.t3.srvr.HttpProxyServlet</servlet-class>
          <init-param>
          <param-name>redirectURL</param-name>
          <param-value>http://www.myiis.com</param-value>
          </init-param>
               <init-param>
          <param-name>Debug</param-name>
          <param-value>ON</param-value>
          <description>Proxy server verbose output.</description>
          </init-param>
          <init-param>
          <param-name>DebugConfigInfo</param-name>
          <param-value>ON</param-value>
          <description>Debug proxy server configuration. Access via /?__WebLogicBridgeConfig</description>
          </init-param>
          </servlet>
          <servlet-mapping>
          <servlet-name>HttpProxyServlet</servlet-name>
          <url-pattern>/</url-pattern>
          </servlet-mapping>
          </web-app>

Yes, you are able to do this using IIS.
          have you checked the settings on your IIS Server?
          also i notice in your proxy servlet that you don't have url mapping for web page extensions? Will this affect it?
          <servlet-mapping>
          <servlet-name>ProxyServlet</servlet-name>
          <url-pattern>/</url-pattern>
          </servlet-mapping>
          <servlet-mapping>
          <servlet-name>ProxyServlet</servlet-name>
          <url-pattern>*.jsp</url-pattern>
          </servlet-mapping>
          <servlet-mapping>
          <servlet-name>ProxyServlet</servlet-name>
          <url-pattern>*.htm</url-pattern>
          </servlet-mapping>
          <servlet-mapping>
          <servlet-name>ProxyServlet</servlet-name>
          <url-pattern>*.html</url-pattern>
          </servlet-mapping>
          <servlet-mapping>
          <servlet-name>ProxyServlet</servlet-name>
          <url-pattern>*.asp</url-pattern>
          </servlet-mapping>
