why not just make the authentication cookie permanent? Here's an other way to do it ... You can then check authentication on the server against the authentication server.

on the client AddOpenIdConnect :

                    OnRedirectToIdentityProvider = context => {
                        context.Properties.RedirectUri = context.Request.Path;
                        return Task.FromResult(0);
                    },
                    OnTicketReceived = context =>
                    {
                        context.Properties.IsPersistent = true;
                        context.Properties.ExpiresUtc = DateTimeOffset.UtcNow.AddDays(15);
                        context.Properties.AllowRefresh = true;

                        return Task.FromResult(0);
                    }
                };
