#1634: How to append a cookie on backend

----------------------+---------------------
 The case is I'd like to add two headers with the same name, but different
 values while processing response from the backend server. More precisely
 under certain circumstances I'd like to append (not set) another Set-
 Cookie header to the original response from my Apache server to eventually
 return two cookies to the client. It seems that "set" action overrides all
 occurrences of the same header.

 Is that somehow possible?
