title: ASP.NET MVC 3 Cookies get lost
body: <p>I am sending domain cookies from one site to my asp.net mvc application , there I setting Authentication cookie , </p>
  
  <p>In My Action Filter I can't see that cookie appears , but if I am looking in BeginRequest event of global.asax there is cookie there. Any Ideas why cookies getting lost on their way to the Action Filter ?</p>

  </code></pre>
  
  <p>doesn't helped...</p>
  
  <p>Don't know what to do with this...
  Update2:
  I can see in Application_BeginRequest - 2 cookies , then when break point hits my custom action filter</p>
  
  <pre><code>public class SecurityFilter : FilterAttribute, IAuthorizationFilter
      {
          public void OnAuthorization(AuthorizationContext filterContext)
          {
  </code></pre>
  
  <p>Here my first cookie dissapearing , and second is still exists.
  the Expire property is set the same for both , and every property except value is the same in both cookies , why the first one gets lost ? and the second is exist ? Reading about ASP.NET MVC request pipeline doesn't opened my eyes on something , anyone please :-)</p>
