input: [Category] Security [Description] This demo shows how to use the IDesign Generic Interceptor framework to propagate the entire stack of callers (their identities, authentication level, operations, etc) in every call. This offers a secure alternative to impersonation, allowing every stop along the call chain to find out the identity of the callers (and the original caller). You still need to protect and sign the stack of callers yourself. the demo uses both IDesign support for managing message headers and the Generic Interceptor framework. The Generic Interceptor framework is nothing short of extensions for the WCF extensions. [Last Updated] 1/24/2009 [Title]
