爲什麼不WsHttpBinding的支持流？

編輯：爲了測試我約NetTcpBinding的評論，我想下面的代碼，這使運行時錯誤：

<netTcpBinding > 
     <binding name="myBinding" transferMode="Streamed">   
      <reliableSession enabled="true"/> 
     </binding> 
</netTcpBinding> 

運行時異常：

Unhandled Exception: System.InvalidOperationException: Transfer mode Streamed is 
not supported by ReliableSessionBindingElement. 
    at System.ServiceModel.Channels.ReliableSessionBindingElement.VerifyTransport 
Mode(BindingContext context) 

如果<reliableSession enabled="true"/>被刪除，代碼工作。

WsHttpBinding doesn't support streaming due to the reliable messaging protocol (WS-RM), which requires that messages are buffered on either end.

如前所述here ...約WS-RM更多信息。

還有另一篇文章here提供的推理不能夠流相對於上述原因...

This is because WS-RM needs to apply signing/checksums to the whole message as a unity, etc; and this is not possible when streamed transferMode, only with buffered transferMode...

此外netTcpBinding實際上利用了WS-RM的可靠性的目的。
