If there are any headers identified in .htaccess files, such as the one in the cache directory for WP Super Cache, those headers, such as Cache-Control are sent back to the browser, along with any headers set in the http nginx.conf.

And? You want to hide this headers from response returned to
client? If yes, please use proxy_hide_header directive, see here:

http://wiki.nginx.org/NginxHttpProxyModule#proxy_hide_header

Yes, proxy_ignore_headers works with response headers returned by
backend server. As I already wrote, it is here to stop proxy
module from processing several specially handled response headers
(if needed for some reason).
