GZip seems to be not working on WildFly-8.2

[valsaraj007]

Hi,

I have configured GZip on WildFly-8.2:

<subsystem xmlns="urn:jboss:domain:undertow:1.2">

                <buffer-cache name="default"/>

                <server name="default-server">

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

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

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

                        <filter-ref name="gzipFilter" predicate="path-suffix['.css'] or path-suffix['.js']" />

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

                        <filter-ref name="x-powered-by-header"/>

                    </host>

                </server>

                <servlet-container name="default">

                    <jsp-config/>

                    <websockets/>

                </servlet-container>

                <handlers>

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

                </handlers>

                <filters>

                    <response-header name="server-header" header-name="Server" header-value="WildFly/8"/>

                    <response-header name="x-powered-by-header" header-name="X-Powered-By" header-value="Undertow/1"/>

                    <gzip name="gzipFilter"/>

                </filters>

            </subsystem>

Then I checked with YSlow and did not found any change in grade. It is still showing grade F.
