  My problem is still actual.
  I am attempting to use http header from fastcgi server as part of cache key.
  $upstream_http_x_language contains value, but empty in cache key

Part of cached page:

KEY: httpGETexample.comfoto-video-audio/videoUAH
▒Expires: Thu, 19 Nov 1981 08:52:00 GMT
Pragma: no-cache
Content-Type: text/html; charset=utf-8
Last-Modified: Wed, 17 Sep 2014 13:59:43 GMT
Cache-Control: private
X-Language: uk
X-Accel-Buffering: yes


key must be
httpGETexample.comfoto-video-audio/videoukUAH
