@ChannelHandler.Sharable
public class HistoryServerStaticFileServerHandler
extends org.apache.flink.shaded.netty4.io.netty.channel.SimpleChannelInboundHandler<org.apache.flink.runtime.rest.handler.router.RoutedRequest>
HistoryServer
that serves requests to web
frontend's static files, such as HTML, CSS, JS or JSON files.
This code is based on the "HttpStaticFileServerHandler" from the Netty project's HTTP server example.
This class is a copy of the StaticFileServerHandler
. The differences are that the
request path is modified to end on ".json" if it does not have a filename extension; when
"index.html" is requested we load "index_hs.html" instead to inject the modified HistoryServer
WebInterface and that the caching of the "/joboverview" page is prevented.
