title: browser sends non existant cookies
body: <p>In my Request Headers, I spotted in the cookie section:</p>
  
  <p><code>cookies: Session: Token-ABC; AnotherCookie: Value-XYZ;</code></p>
  
  <p>These cookies are NOT existing in my cookie jar.</p>
  
  <p>When I perform an action which triggers a <code>Set-Cookie</code> action, such as <code>Log In</code>, I have the corresponding cookies set in my cookie jar.</p>
  
  <p>Afterwards, when I send a request, I actually send the same TYPE of cookie, TWO times:</p>
  
  <p><code>cookies: Session: Token-ABC; AnotherCookie: Value-XYZ; Session: Token-DEF; AnotherCookie: Value-UVW;</code></p>
  
  <p>This severely interferes with the dependant mechanism.</p>
  
  <p>I tried clearing the browser cache and restarting it. No go.</p>
  
  <p>The Site is served using the AWS CloudFront service. I also tried to mess with the <code>Object Caching</code> settings, switched it to <code>customize</code> and made sure <code>Cookie Forwarding</code> is set to <code>None</code>.</p>
  
  <p>This also occures to me in <code>FireFox</code>, as I was testing things using that browser too.</p>
  
  <p>I tried <code>Opera</code> too, only when my testings were done and my newly created cookies were well received and stored. Therefore <code>Opera</code> remained "fresh" and did not cache any cookie values, and the dependant mechanisms worked as expected (no dups sent)</p>
  
  <p>Anyone familiar with this?</p>
