【问题描述】：

压缩启用了消息安全的 WCF 服务的通信的最佳做法是什么，它不是托管在 IIS 上并使用 HTTP 作为传输协议？

在我的搜索中，我发现了在消息被保护后应用压缩的通道级别的实现（因此压缩不是最佳的）。

你能指出我正确的方向吗？ 甚至更好：您知道在安全协议运行之前应用的任何 WCF 压缩实现（使用消息安全性）吗？

【参考方案1】：

您可以使用 Microsoft Sample Compression (Microsoft WCF Samples\WCF\Extensibility\MessageEncoder\Compression)，并且可以将 Message Security as TripleDesSha256 算法用作此配置。
