Redirect loop problems

[Dewangga Bachrul Alam]

Hi,

Today, I was implement redirect using return 301, here's my snippet:

server {
        listen 80;
        server_name domain.tld;
        error_log       /dev/null;
        access_log      off;
        return 301 https://www.domain.tld$request_uri;
}

server {
	listen 80;
	server_name www.domain.tld;
        error_log       /dev/null;
        access_log      off;

location ^~ /go/ {
	# Apache2 Backend
	proxy_pass http://127.0.0.1:8080
}
location / {
	return 301 https://$http_host$request_uri$is_args$query_string;
}
}

server {
        listen 443 ssl spdy;
        server_name     domain.tld;
        return 301 https://www.domain.tld$request_uri;

        error_log       /dev/null;
        access_log      off;

        ssl on;
        ssl_certificate         bundle.crt;
        ssl_certificate_key     file.key;
        ssl_verify_depth 2;
}

server {
	listen 443 ssl spdy;
	server_name www.domain.tld;
location ^~ /go/ {
	return 301 http://$http_host$request_uri;
}
location / {
	# Apache2 Backend
	proxy_pass http://127.0.0.1:8080
}
}

The problem is, if the visitor hit `/go/` URL, the browser says it's
redirect loop, but if I try `curl -I` command the `/go/` URL, it's
normal, and says HTTP 200.

Any hints? Really appreciate any helps.
