Use A Dos Filter http://wiki.eclipse.org/Jetty/Reference/DoSFilter. To enable it in Jetty.xml you would insert this code

<filter>
   <filter-name>DoSFilter</filter-name>
   <filter-class>org.eclipse.jetty.servlets.DoSFilter</filter-class>
   <init-param>
     <param-name>maxRequestsPerSec</param-name>
     <param-value>30</param-value>
   </init-param>
</filter>
