Bayeux中的multi-frame的行为

 
阅读更多

一般来说一个client对server只有2个connect.一个收一个发.
如果开2个tab的情况, 则让2个tab各保持一个连接.
对于server端来说是这样的,根据cookie来判断是否multiframe,
如果发现是multiframe, 则改用传统的polling,就是每收到client的connect请求,就给一个response,里面带着advice有建议的interval.这样client就可以定期发送connect给server

如果不是multiframe,则server端收到connect后,会一直等到有event message才返回响应,
如果是, 则server会在收到connect后马上返回response,同时带上event message.
