如果你在IE(or Firefox)里同时在多个tab来access a?flex application that uses messaging with a streaming AMF connection，就会出现下列error
cannot grant streaming connection to FlexClient with id '' because max-streaming-connections-per-session limit of '1' has been reached....
注意：在google chrome里不会有这个问题
原因是：By default,BlazeDS uses 1 as the value for max-streaming-connections-per-session. 解决办法是在service-config.xml里修改"max-streaming-connections-per-session" property的设置for Internet Explorer and Firefox.
例：把"max-streaming-connections-per-session" property设置为8
