title: .aspxauth Not being used
body: <p>When I use the following code:</p>
  
  <pre><code>FormsAuthentication.SetAuthCookie(userId.ToString(), true);
  </code></pre>
  
  <p>an .aspxauth cookie is created with a correct expiration date.</p>
  
  <p>However when i close all instances of the browser and return to the page, I am no longer logged in. I also do not see the cookie in firebug. When I search for the cookie in the browser (I choose remove a cookie, and search for .ASPXAUTH) I do see that it is there.</p>
  
  <p>Any clues for this behavior? Thanks!</p>
  
  <p>In the web.config:</p>
  
  <pre><code>authentication mode="Forms"
  forms timeout="28800" 
  authentication
  </code></pre>
