title: Deliver P3P http headers for IE-8
body: <p>we built a webapp. On IE we need to allow third party cookies. We are using Java Server Faces. Anyway we are looking for the best way to deliver the P3P-Header? We thought about Apache configuration files. Is it possible to detect InternetExplorer on this level or is it better to check for browser in the application?</p>
  
  <p>Thanks in advance.</p>
