WCF message security with compression

What is the best practice for compressing the communication of a WCF service having message security enabled, that is not hosted on IIS and uses HTTP as transfer protocol?

In my searching开发者_开发百科 I found implementations made at channel level that apply compression after the message was secured (so the compression is suboptimal).

Can you point me in the right direction? Or even better: Do you know any WCF compression implementation (working with message security) that is applied before security protocol run?

You can use Microsoft Sample Compression (Microsoft WCF Samples\WCF\Extensibility\MessageEncoder\Compression) and you can use Message Security as TripleDesSha256 algorithm as this config.
