Can a custom UserNamePasswordValidator add things to the WCF session?

Question

Related to this question, I'm instantiating a connection to our internal API inside my custom UserNamePasswordValidator. Can I stash this somewhere so that I can use it in future calls in that user's session?

This is similar to this question, but I'm not using IIS, so I can't use HttpContext.Current (or can I?).

Update: Some context: our internal API is exposed via a COM object, which exposes a Login method. Rather than have a Login method in my service interface, I've got a custom UserNamePasswordValidator, which calls the Login method on the COM object.

Because instantiating the COM object and logging in is expensive, I'd like to re-use the now-logged-in COM object in my service methods.

Answer 1

UserNamePasswordValidator is absolutely out of all WCF contexts. It is only used to validate user name and password. Can you futher explain your problem?

Edit: I guess COM object is instantiated for each session, isn't it? Otherwise wrapping COM into singleton should solve your problem. If you need to have per session COM object shared between validator and service instance you will need some cache or registry - something which is outside both validator and service and can be called from both of them.

Answer 2

Yes, it can.
