Lets suppose you are sign in and you have and controller account and view index
so when first time render https://abc.com/account/index, now you capture this request into fiddler.
you get response http 200 and some data lets suppose "hello world"
Next you call logout end point in your web app and its run following code mentioned below
IEnumerable authTypes = HttpContext.GetOwinContext().Authentication.GetAuthenticationTypes();
HttpContext.GetOwinContext().Authentication.SignOut(authTypes.Select(t => t.AuthenticationType).ToArray());
in fiddler it show it has called something
repeat step 1
again you get response http 200 and some data lets suppose "hello world" instead of http 401
that is very frustrated....
