此方案的优势在于，虽然请求方仍然必须知道使用了某种类型的轮询机制，但服务本身并不必如此。
There are already several polling solutions popping up various specifications, so clearly there is a need for this type of solution.
目前存在多个轮询解决方案以及各种规范，这种现象清楚地说明了人们迫切地需要这种类型的解决方案。
All server and client implementations MUST support the "long-polling" connection type and SHOULD support "callback-polling". All other connection types are OPTIONAL.
所有服务端和客户端实现必须支持“长轮询”连接类型，并且应该支持“回调轮询”。其他连接类型都是可选的。
