-------------------------------------------------------------
I'm sure. The request url from the original (copied) {{HttpServletRequest}} is
{{null}}.
Note that the original request is of type
{{org.apache.wicket.protocol.ws.javax.JavaxUpgradeHttpRequest}} and its
requestURL is {{null}} but its requestUri is
{{/chystat/wicket/websocket?pageId=13&wicket-ajax-baseurl=monitoring%2Foverview%3F13&wicket-app-name=chystat.wicket}}
