asp.net cache sharing between main site add its applications/virtual directories (using iis 7.5)

Question

My solution contains 4 projects: Core, Data (libraries), Admin, Client (MVC 3 sites).

Admin and Client communicate with DB with Data project's repositories.

I want to cache data in Data project using HttpContext.Current.Cache for both Admin and Client and invalidate cached data after updates that can appear both in Admin and Client.

How should I configure sites, applications or virtual directories and app pools to have the same cache in Client and Admin?

Answer 1

You can't share the standard ASP.NET cache across applications. However, you can use tools like memchached or Velocity by Microsoft.
