WCF RIA Services and communicating via SSL

I have a simple Silverlight application that use WCF RIA Services to communicate with the ASP.NET application on my web server. By default I assume that this communication is plain and not encrypted in any way.

How do you request it use SSL or some other m开发者_开发问答ethod to ensure that all data via the WCF RIA Service is secure?

On a domain service you can specify in the EnableClientAccess attribute that only secured transport is allowed.

ie.

[EnableClientAccess( RequiresSecureEndpoint = true )]
