使用代理时，bayeux长轮询彗星〜失败

Question

我试图在SalesForce中使用Streaming API，它基本上是使用Comet / Long Polling技术实现的。在客户端，我们使用Java与jetty-http，bayeux-api，cometd-java-client

如果我们运行没有代理的应用程序，一切都很完美。但如果客户端正在使用网络代理

答：它能够进行用户身份验证

B.长轮询握手成功

C. meta / connect最初有402错误（参见下面的日志）但最终成功

D.永远不要从服务器端得到任何响应

任何想到这里发生了什么，以及为什么代理导致了这一点，即使上面的A，B，C中的所有HTTP连接请求都成功了？

可能是代理正在缓冲响应的情况。它发生在例如使用nginx和proxy_buffering on指令。
