Question

我只是构建了一个小型PoC，其中我使用带有http / 2的Jetty 9.3.9.M1嵌入式服务器和带有Apache Wicket的PushBuilder API将资源推送到客户端。

我使用以下服务器设置：

Server server = new Server();

// HTTP Configuration
HttpConfiguration http_config = new HttpConfiguration();
http_config.setSecureScheme("https");
http_config.setSecurePort(8443);
http_config.setSendXPoweredBy(true);
http_config.setSendServerVersion(true);

// keytool -keystore keystore -alias jetty -genkey -keyalg RSA
SslContextFactory sslContextFactory = new SslContextFactory();
sslContextFactory.setKeyStorePath(new File(".","keystore").getCanonicalPath());
sslContextFactory.setKeyStorePassword("123456789");
sslContextFactory.setKeyManagerPassword("123456789");
sslContextFactory.setCipherComparator(HTTP2Cipher.COMPARATOR);
sslContextFactory.setUseCipherSuitesOrder(true);

// HTTPS Configuration
HttpConfiguration https_config = new HttpConfiguration(http_config);
https_config.addCustomizer(new SecureRequestCustomizer());

// HTTP Connector
ServerConnector http1 = new ServerConnector(server, new HttpConnectionFactory(http_config),
    new HTTP2CServerConnectionFactory(http_config));
http1.setPort(8080);
server.addConnector(http1);

// HTTP/2 Connection Factory
HTTP2ServerConnectionFactory http2 = new HTTP2ServerConnectionFactory(https_config);

NegotiatingServerConnectionFactory.checkProtocolNegotiationAvailable();
ALPNServerConnectionFactory alpn = new ALPNServerConnectionFactory();
alpn.setDefaultProtocol(http1.getDefaultProtocol());

// SSL Connection Factory
SslConnectionFactory ssl = new SslConnectionFactory(sslContextFactory, alpn.getProtocol());

// HTTP/2 Connector
ServerConnector http2Connector = new ServerConnector(server, ssl, alpn, http2,
    new HttpConnectionFactory(https_config));
http2Connector.setPort(8443);
server.addConnector(http2Connector);

WebAppContext webAppContext = new WebAppContext();
webAppContext.setServer(server);
webAppContext.setContextPath("/");
webAppContext.setWar("src/main/webapp");
server.setHandler(webAppContext);

ContextHandlerCollection contexts = new ContextHandlerCollection();
contexts.addHandler(webAppContext);
server.setHandler(contexts);

ALPN.debug = false;

server.start();
server.join();

现在我面临的问题是，当我对这样的资源发出http / 1.1请求时：

http://127.0.0.1:8080/wicket/resource/de.jetty.wicket.http2.example.resources.TestResourceReference/TestResourceReference-ver-1463040221000.css

状态代码304在第二个请求之后显示在chrome调试器中

如果我对同一资源发出http / 2.0请求：

https://127.0.0.1:8443/wicket/resource/de.jetty.wicket.http2.example.resources.TestResourceReference/TestResourceReference-ver-1463040221000.css

状态代码200显示在每个请求上 - 似乎客户端没有缓存它。

亲切的问候，并提前感谢。
