System.Web.Cache, Session level or Application level

Question

Random quick question.

The System.Web.Cache class, at what level is the information stored? On a per session level or whole application level?

Thanks

Answer 1

AFAIK at the application level.

http://msdn.microsoft.com/en-us/library/system.web.caching.cache.aspx

From the page:

One instance of this class is created per application domain, and it remains valid as long as the application domain remains active.

Answer 2

An instance of the cache is per app domain
