Query strings duplicating on 301 redirect

Server NGINX
1

Hey All,

I am trying to redirect (301) all HTTP request to TLS (HTTPS) and I keep
getting duplicate query strings added to the uri. e.g.:

curl -I “http://foo.bar.example.com/foobar.css?v=2”
HTTP/1.1 301 Moved Permanently
[clipped]
Location: http://foo.bar.example.com/foobar.css?v=2?v=2

Nginx config:

location / {
if ($scheme = http) {
rewrite ^ https://$http_host$request_uri permanent;
}

Any ideas?

Thanks in advance.

Second last paragraph looks like it should fix it.

Just a note, I think the preferred way to do this is with “return”. It’s
much simpler (no rewrite / PCRE overhead):

location / {
if ($scheme = http) {
return 301 https://$http_host$request_uri;
}
