I use nginx/1.4.4 with gunzip = on and gzip_vary = on. This leads to a
duplicate Vary Header.
gzip_vary should do nothing if the header is already present:
[email protected]:~$ curl -I
HTTP/1.1 200 OK
Date: Sun, 19 Jan 2014 11:30:59 GMT
I have no control of the upstream server it may send a Vary header or
in order to be safe I would like to use gzip_vary = on in order to
any problems here.
This issue is in standard ngx_http_header_filter_module so can anyone
