    wildfly-10.0.0.Final LearningPushHandler

    Stan Golemanov Newbie

      Hi,

       

      as i am trying to assess the performance using server push in http/2, having difficulties to setup LearningPushHandler.

       

      in standalone.xml, configuration is as follows:

       

      <subsystem xmlns="urn:jboss:domain:undertow:3.0">

                  <buffer-cache name="default"/>

                  <server name="default-server">

                      <http-listener name="default" socket-binding="http"/>

                      <https-listener name="default-https" security-realm="httpsRealm" socket-binding="https" enable-http2="true"/>

                      <host name="default-host" alias="localhost">

                          <location name="/" handler="welcome-content"/>                                     

        <filter-ref name="server-push" />

                      </host>

                  </server>

                  <servlet-container name="default">

                      <jsp-config/>

                      <websockets/>

                  </servlet-container>

                  <handlers>

                      <file name="welcome-content" path="${jboss.home.dir}/welcome-content"/>

                  </handlers>

                  <filters>

        <filter name="server-push" class-name="io.undertow.server.handlers.LearningPushHandler"  module="io.undertow.core">

        <param name="max-age" value="120"/>

        <param name="max-entries" value="1200"/>

           </filter>

                  </filters>

              </subsystem>

       

      and there is an error while accessing the web page:

       

      2016-05-26 13:42:20,390 ERROR [io.undertow.request] (default I/O-5) UT005071: Undertow request failed HttpServerExchange{ GET /bg;jsessionid=altr0DCUcqiOa3MdI68NhboMsfHlhWLf_TpSvVfq.stan-pc request {accept=[text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8], accept-language=[bg-BG,bg;q=0.8,en;q=0.6], cache-control=[max-age=0], accept-encoding=[gzip, deflate, sdch], user-agent=[Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36], upgrade-insecure-requests=[1], Host=[localhost:8444]} response {}}: java.lang.RuntimeException: WFLYUT0064: Failed to configure handler class io.undertow.server.handlers.LearningPushHandler

              In its current form, it doesn't look like you can use that filter in the WildFly undertow subsystem's filters. I have submitted a PR to undertow project Add a convenience constructor to LearningPushHandler by jaikiran · Pull Request #405 · undertow-io/undertow · GitHub to allow this to work. If it gets accepted, you should be able to configure it in WildFly, in an upcoming release.

                you could use expression-handler to configure this instead of custom-handler

                 

                something like

                 

                <expression-filter name="learning-push" expression="learning-push" />

                  @ jaikiran pai : thanks

                   

                  @ Tomaz Cerar: tried as you suggested, there was no error, but i am not sure of the result as i did not saw any server push in F12 network console
