I know there is a delegate 'MvcSubstitutionCallback' which has the following signature : public delegate string MvcSubstitutionCallback(HttpCo...

Looks like context parameter of asp:net substitution control method is missing the current session once the page is output cached.

I am using Html.RenderAction<CartController>(c => c.Show()); on my master Page to display the cart for all pages. The problem is when I add an item to the cart and then hit the browser back button.

I'm building a custom page caching utility that uses a syntax like {Substitution:GetNonCachedData} to get data that's not supposed to be cached.
