ASP.NET MVC - CustomeAuthorize filter action using an external website for loggin in the user

Question

I have a CustomeAuthorize action filter that forwards the user to signin page if user is not authenticated. I apply this filter to actions or controllers.

Answer 1

Use the RedirectResult similar to how you were using the RedirectToRouteResult before to replace the result in the filter context.

filterContext.Result = new RedirectResult("http://externalSite.com/login?returnUrl=" + filterContext.HttpContext.Request.RawUrl );

Answer 2

Let me see if I understand - you have an iFrame, and executing an action within this iFrame. You want to redirect to a parent page, not within that iFrame?

If so, just use Redirect(url) in your action.

Answer 3

You can add a judgement by jQuery on the login page.

$(function () {
        if (window != top) {
            top.location.href = location.href;
        }
    });   

OR

edit 'filterContext.Result' in action 'OnActionExecuting'

filterContext.Result = new ContentResult() { Content = "<script>top.window.location.href='/user/Login'</script>" };
