title: Custom headers on Amazon S3
body: <p>Is it possible to have custom headers on Amazon S3 with arbitrary naming?</p>
  <p>For example, I am using a CDN pointing to Amazon S3 as the origin server, and in order to enable advanced functionality on the CDN I need to use a custom header <code>x-something-something</code>...</p>
  <p>I see it's possible to do this with <code>x-amz-meta-(something)</code> but what about something more general like <code>x-(something)-(something)</code> without the <code>amz</code>?</p>
