WCF郵件安全與壓縮

Question

什麼是壓縮WCF服務的通信的最佳做法是啓用郵件安全，這不是託管在IIS上並使用HTTP作爲傳輸協議？

在我的搜索中，我發現通道級別的實現是在消息被保護後應用壓縮（所以壓縮不是最理想的）。

您能否指點我正確的方向？ 甚至更​​好：您是否知道在安全協議運行之前應用的任何WCF壓縮實施（使用消息安全性）？

您可以使用Microsoft示例壓縮（Microsoft WCF Samples \ WCF \ Extensibility \ MessageEncoder \ Compression），並且可以使用Message Security作爲此配置的TripleDesSha256算法。
