CookieAuthenticationOptions, ExpireTimeSpan does not work

Question

I have the following code:

    public void ConfigureAuth(IAppBuilder app)
    {
        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            


        

Answer 1

It does expire.

Make sure you do not have any background ajax activity as it extends the session (SlidingExpiration is true by default).

Also I had to manually delete the old cookie after I changed ExpireTimeSpan from the default 14 days to a smaller value.
