title: How to deny direct url access to files on Jetty
body: <p>I'm running webapps on Jetty. I have set "dirAllowed" to "false" to disable the directory browsing on the defined contextpath by 
  webAppContext.setInitParameter("org.eclipse.jetty.servlet.Default.dirAllowed", "false"). </p>
  
  <p>But, users can still access other files (not located on the contextpath) through url (eg. <a href="http://somehost.yahoo.com:8081/abc.xml" rel="nofollow">http://somehost.yahoo.com:8081/abc.xml</a>) and abc.xml is located under the root directory of the Jetty server. </p>
  
  <p>Is there a way to block/deny direct url access to files located on Jetty? Thanks!</p>
