I want to know best practice on how to create Shopping cart using MVC 5 Owin Identity with support anonymous users.
Example: So both logged in and anonymous user can select products. For logged in user all is ok, I have userId and can create cart for him. What I must do for anonymous user? How I can create cart for him?
Please help.
Result of my investigation is so that it is bad to use Session with Owin & Identity.

My variant is to create temp cookie for shopping cart with cartId.
When user logging in I'm checking if cookie for shopping cart exists and if so I attach all files to user cart. In other case I'm taking user cart id to cookie if cart id exists.
