title: Where does TempData store its data?
body: <p>There is a <a href="https://stackoverflow.com/questions/15004081/where-does-tempdata-get-stored">similar question</a> from years ago regarding the old ASP.NET.  I was wondering whether it's different for .NET Core.  </p>
  
  <p>In the linked question, it states that TempData is stored in Session, which by default is tied to a single server.  So to make it work on server farm, I'd have to utilize a State Server of some type.</p>
  
  <p>Has this behavior changed with .NET Core to better support web farms?</p>
