title: Is it acceptable to have multiple `set-cookie` headers in an HTTP/2 stream?
body: <p>I'm proxying HTTP/2 client -> HTTP/1.1 server, and I'm not sure how to handle multiple <code>set-cookie</code> in the response.</p>
  
  <p>I believe <code>set-cookie</code> is the only header which is allowed to be set multiple times for HTTP/1.1 - is this the case for HTTP/2 as well?</p>
  
  <p>If I receive <code>set-cookie</code> multiple times in the HTTP/1.1 response, how do I send that back to the client over HTTP/2? Can I merge it together into a single header, or do I need to send multiple <code>set-cookie</code> headers back via HTTP/2.0?</p>
