I don't think it can. But pretty easy with Nginx::Perl:

use Nginx;
use Nginx::HTTP;

sub init_worker {
    ...
    my $req = "GET / HTTP/1.1" . "\x0d\x0a" . "Host: foobar" .
"\x0d\x0a\x0d\x0a" ;

    ngx_timer 0, 5, sub {
        ngx_http "1.2.3.4:80", $req, sub {
            my ($headers, $buf_ref) = @_;

            unless ($headers) {
                ngx_log_error $!, "error";
                return;
            }

            ngx_log_notice 0, "got $headers->{'_status'}";
            ...
        };
    };
}
