Using nginx to rewrite cookies and requests for services - like f.ex. FreeIPA

Just a small snippet to get you started.

Placeholders, for the example:
int.server == internal server name
frontend.server == this server server

The actual example:

        location / {
                proxy_ssl_name int.server;
                proxy_ssl_verify off;
                proxy_cookie_domain int.server frontend.server
                proxy_http_version 1.1;
                proxy_buffering off;
                set  $referer  $http_referer;
                if ($http_referer ~* ^https://frontend.server/(.+)$) {
                        set $referer https://int.server/$1;
                }
                proxy_set_header Referer $referer;
                proxy_pass https://int.server;
        }

I haven't had the time to make something work with multiple backends - it seems like the grammar in nginx is lacking - will try again with another approach in the future.
