Question

我正在尝试在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

一个。它能够进行用户身份验证

B中。长轮询握手是成功的

℃。 meta / connect最初有402错误（参考下面的日志）但最终成功

d。 永远不会收到服务器端的任何回复

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A，B，C中的所有HTTP连接请求都成功了？
