Hello,
I must install glpi (in http) and I want to disable redirections of nginx from http to https.
I saw in the file /etc/nginx/sites-available/00-default.conf the last line:
# Redirect all insecure http:// requests to https://
    return 301 https://$host$request_uri;
But when I comment the last one, then reload and restart nginx, the redirection from http ==> https is again active.
Any idea?
thank you.
