title: ASPx set Cookie Domain
body: <p>I have a code as follows:</p>
  
  <pre><code> this.Response.Cookies.Add(new HttpCookie("COOKIENAME",'test'));
  </code></pre>
  
  <p>I want to add the domain ".test.com" for this cookie. How do I do so? I tried the standard:</p>
  
  <pre><code>    this.Response.Cookies["COOKIENAME"].Domain = ".test.co.uk";
  </code></pre>
  
  <p>But the cookie is not being set for the whole domain. Any suggestions?</p>
  
  <p>The following is not working either:</p>
  
  <pre><code>HttpCookie MyCookie = new HttpCookie("COOKIENAME");
          MyCookie.Value = 'test';
          MyCookie.Domain = ".test.co.uk";
  
          this.Response.Cookies.Add(MyCookie);
  </code></pre>
