How do I exclude a property from being cached?

Question

I’m caching an object but noticed that one of the properties is being combined with the parent object when it is supposed to only get its value if the object requests it after the initial caching procedure has occurred. So my two questions are:

1. Why does the cache provider not just use the property variables (not the property function) to cache the object as these are what really make the object what it is?
2. How do I exclude one of these properties from being wrapped up in the cached object?

Is there some markup that I can use to indicate that the item can’t be cached similar to the nonserializable markup?

Private _SomeInfo As SomeInfo ‘(Can be cached)
Public Property SomeInfoProperty() As SomeInfo ‘(Should not be cached)
    Get
       If _SomeInfo Is Nothing Then
          _SomeInfo = SomeInfo.GetData()
       End If
       Return _SomeInfo
    End Get
    Set(ByVal value As SomeInfo)
       _SomeInfo = value
    End Set
End Property
