I am trying cache for my website use Nginx Proxy module and has following requirements:

If request has cookie (in request header)

• The response will use cache of Nginx
• Hide Set-Cookie header line

If request has no cookie (in request header)

• Foward request to backend
• Don't hide h Set-Cookie header line

I use If (of rewrite module) and any directive:

if (!-e $http_cookie) 
{
  set $not_cache_rq 0;
  set $not_cache_rp 0;
}
if ($http_cookie) {
  set $not_cache_rq 1;
  set $not_cache_rp 1;
}
proxy_cache_bypass $not_cache_rq;
proxy_no_cache $not_cache_rp;
proxy_hide_header  Set-Cookie;

I do not know how to call cookie proxy_hide_header option when has cookie and no cookie on header line.

Please help me. Many thanks.
