	Module  Name :

		context.h

	Abstract:
		A class to retrieve and release ASP intrinsics.  This class encapsulates the new way
		of getting access to ASP instinsic objects.  It does away with the need for OnStartPage
		and OnEndPage methods, and, by doing so, gives Application scope objects access to the
		intrinsics.  The intrincis should never be retained across calls, as the context may
		change between calls.
