Question

在服务器崩溃或间歇性网络故障后，Atmosphere Web套接字客户端能够重新连接到服务器并接收消息。但是，大气长轮询客户端（IE8）无法重新连接。

我的应用是一个实时事件浏览器，可以订阅主题并显示所有应用程序事件。 Chrome和Firefox工作得很好，但不幸的是，我们仍然需要支持IE8，因此WebSocket和Long-Polling之间的一致行为至关重要。我在这里错过了什么？这是一个Atmosphere bug ??

如何重现

下载氛围聊天示例v2.0.3 http://search.maven.org/#artifactdetails%7Corg.atmosphere.samples%7Catmosphere-chat%7C2.0.0%7Cwar
修改application.js以使用长轮询并以5秒的间隔永久重新连接。

运输：'长轮询' 重新连接：真，
maxReconnectOnClose：Number.MAX_VALUE
启动Tomcat服务器并开始聊天
突然停止Tomcat
启动Tomcat
打开另一个浏览器并发送一些消息。
原始浏览器不会收到消息。
