There is a setUsingCookies method that needs to be called on the WebApplicationHandler object. This
can be called from your usual Jetty xml configuration file when you configure your web-app:
<Call name="addWebApplication">
<Arg>/jetty/*</Arg>
<Arg>/demo/webapps/jetty</Arg>
<Call name="getWebApplicationHandler">
<Set name="usingCookies">false</Set>
</Call>
</Call>
