Nginx too many redirect when trying to redirect non www to www
Solution 1:
You need to have separate server blocks for your www and non-www domains.
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
ssl_certificate ...
ssl_certificate_key ...
server_name example.it;
return 301 https://www.example.com$request_uri;
}
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
ssl_certificate ...
ssl_certificate_key ...
server_name www.example.it;
... rest of configuration ...
}
