If the server implementation supports subsessions, they must derive from this class.

WARNING: Because this class derives from CObject you must not simply delete an instance of a class derived from this class (ie. your subsession), instead you MUST Close() it.

In practise this probably means you need a ConstructL like this:- CFred *self = new(ELeave) CFred(....); CleanupClosePushL(*self); // Note use of CleanupClosePushL and of *self self->ConstructL(...); CleanupStack::Pop(self); // Note use of *self instead of self
