    # Connection handling

    proxy_set_header Connection "";

    # Do the upstream request

    #proxy_pass http://example.org;

    #proxy_pass http://debugger_upstream;

    proxy_pass "${scheme}://${subdomains}${upstream_domain}${requested_uri}";

    # Do the upstream request, forcing HTTPS

    #proxy_pass https://example.org;

    #proxy_pass https://debugger_upstream;

    #proxy_pass "${scheme}://${subdomains}${upstream_domain}${requested_uri}";

    proxy_pass "https://${subdomains}${upstream_domain}${requested_uri}";
