body: <p>Can I update cookies in the configuration of a NSURLSession after the creation of the session?</p>
  
  <p>I use this code to update the cookies but it doesn't seem to work.   </p>
  
  <pre><code>self.session = [NSURLSession sessionWithConfiguration:config delegate:self delegateQueue:nil];
  self.session.configuration.HTTPShouldSetCookies = NO;
  self.session.configuration.HTTPCookieAcceptPolicy = NSHTTPCookieAcceptPolicyAlways;
  self.session.configuration.HTTPAdditionalHeaders = [NSHTTPCookie requestHeaderFieldsWithCookies:cookiesArray];
  </code></pre>
  
  <p>Thanks,</p>
