title: Is the name of a cookie case sensitive?
body: <p>A HTTP Cookie consists of a name-value pair and can be set by the server using this response:</p>
  
  <pre><code>HTTP/1.0 200 OK
  Content-type: text/html
  Set-Cookie: name=value
  Set-Cookie: name2=value2; Expires=Wed, 09 Jun 2021 10:18:14 GMT
  </code></pre>
  
  <p>Future requests from the client will then look like this:</p>
  
  <pre><code>GET /spec.html HTTP/1.1
  Host: www.example.org
  Cookie: name=value; name2=value2
  </code></pre>
  
  <p>Is the name of the cookie case sensitive?</p>
  
  <p>For example, if my server sends a response as such:</p>
  
  <pre><code>HTTP/1.0 200 OK
  Content-type: text/html
  Set-Cookie: Aaaa=Bbbb
  Set-Cookie: aAaa=bBbb
  Set-Cookie: aaAa=bbBb
  Set-Cookie: aaaA=bbbB
  </code></pre>
  
  <p>Is it reasonable to expect a client (Chrome, FireFox, Safari, IExplorer, Opera, etc) to send future requests with the header <code>Cookie: Aaaa=Bbbb; aAaa=bBbb; aaAa=bbBb; aaaA=bbbB;</code>?</p>
