WCF RIA Services and persistant / static variables outside of session

Question

I am wondering if there is a way to persist variables in the business layer once the clients session has ended in WCF RIA Services. The challange is we are going to be loading a fair amount of data into caching but want the cache to persist, and allow the silverlight client to connect to the cache without recreating it and reloading all the data.

Any ideas or work arounds?

Thank you, Derrick

I presume the service is hosted on IIS. You can set the ASPNET compatibility on in a web service and then can use Application and Session variables.

Set this in Web.config: <serviceHostingEnvironment aspNetCompatibilityEnabled=”true” />
