Are you using ProxyServlet ? http://download.eclipse.org/jetty/stable-9/apidocs/org/eclipse/jetty/proxy/ProxyServlet.html
or AsyncProxyServlet ? http://download.eclipse.org/jetty/stable-9/apidocs/org/eclipse/jetty/proxy/AsyncProxyServlet.html Generally, accessing the raw Jetty internal Request object is a bad idea. There so many potential levels and wrappers in the way that accessing that object is often impossible or impractical from a filter. If you can use the ServletRequest and/or HttpServletRequest then do so. It might make more sense to just use the AsyncProxyServlet instead. Also note that the HttpChannel concepts are not guaranteed to be the same once HTTP/2 is in the picture. Since with HTTP/2 you have 1 physical connection with multiple HTTP/2 streams + requests. We're still working on HTTP/2, so this statement isn't written in stone.
