I have an ASP.NET Web API project, and recently added both local and external OAuth login (using this question as a base). Now, the login is working, but what I worry about now is the expiration date of the tokens. If I understand correctly, Facebook's tokens expire after 60 days, so that means that after two months I should be refreshing the tokens.
But, now my question is, does ASP.NET Web API handle this refresh process for me? Or do I have to add my own logic? I ask because the tutorials are not clear about what to do. They just tell you to enable the Facebook auth and that's it.
