title: Really weird Cookie header behaviour? - Cookies
body: <p>I'm using Firefox 3.6.8 for these tests.</p>
  
  <p><strong>I'm setting a cookie within the response headers</strong> of my web app using:</p>
  
  <pre><code>Set-Cookie: session=7878dfdsfjsdf89sd89f8df9
  </code></pre>
  
  <p>This <strong>does not seem to override</strong> the session Cookie.</p>
  
  <hr>
  
  <p>When a request is performed instead Firefox even sends <strong>duplicate cookies</strong>:</p>
  
  <pre><code>Cookie: session=7d75cd8f55895cbccb0d31ee07c7afc0; 
          session=671e8448a5cebda0442005a186cf69a3; 
          4cb6f2d75c9ffc8916cb55bcbaafecd8
  </code></pre>
  
  <hr>
  
  <p><strong>What is going on??
  Any ideas would be great!! =)</strong></p>
  
  <hr>
  
  <p>This is quite disastrous in my case... if someone could explain what's going on it would really help me out!</p>
