title: Asp.net identity caching for azure ad
body: <p>The issue that currently we are facing is our users in China have delay in signing into Azure Ad.
  I want to create an Asp.net application that acts as an identity service provider for other applications.
  I want my users to login to my application using their Microsoft live accounts and my application should be able to cache the identities to avoid delay.
  Is it possible to implement such a solution?</p>
