How do I manually delete a cookie in asp.net MVC 4

Question

I need to delete authentication cookie manually (Instead of using FormsAuthentication.SignOut whcih for some reasons does not work). I tried

System.Web.Http         


        

Answer 1

Try:

if ( Request.Cookies["MyCookie"] != null )
{
    var c = new HttpCookie( "MyCookie" );
    c.Expires = DateTime.Now.AddDays( -1 );
    Response.Cookies.Add( c );
}

More information on MSDN.

Answer 2

c.Expires = DateTime.Now.AddDays(-1); This does not clear cookies instantly.

Use this: c.Expires = DateTime.Now.AddSeconds(1); This will clear cookies instantly.
