I'm running the latest development version of nginx and gzipping is working. But no Vary Accept-Encoding header is added to any gzip response. The gzip_http_version isn't affecting the behavior, no matter if I set it to 1.0 or 1.1 no header is sent. Even if I add the header myself via the add_header directive, nothing.

If I use PHP to add the header it's there. Any ideas what the problem could be?

My configure options: https://github.com/MovLib/www/blob/master/conf/install-scripts/nginx.sh
My configuration: https://github.com/MovLib/www/tree/master/conf/nginx
Specifically the gzip configuration: https://github.com/MovLib/www/blob/master/conf/nginx/conf/gzip.conf
