Hello.
I did not write this code... 
as I said this code is from 
https://github.com/GoogleCloudPlatform/java-docs-samples/tree/master/appengine-java8/endpoints-v2-guice


Can you explain the  comment from this code... 

    <!--
      URL Pattern /_ah/api/* instead of /* because a legacy v1 servlet uses
      the route /_ah/api/ and using /* will erronously use the legacy v1
      servlet instead of routing to your API.
    -->
    <filter-mapping>
        <filter-name>guiceFilter</filter-name>
        <url-pattern>/_ah/api/*</url-pattern>
    </filter-mapping>


 (I used the legacy endpoint, I moved to endpoint framework, now I am 
trying to use GUICE)
