title: cookie creation with full domain name
body: <p>I am trying to create cookie with domain : ausserver.company.com and it is not getting created.<br>
  I tried with company.com and it works.</p>
  
  <pre><code>var cookie = new HttpCookie("cookie name");
   cookie.Domain = "auscc.company.com";
   Response.Cookies.Add(cookie);
  </code></pre>
  
  <p>I also did see that there are couple of cookies like JSESSIONID which has cookie host = "auscc.company.com".
  I dont know how are they created?</p>
  
  <p>Does anyone know why?</p>
