How to redirect from www to non-www with ssl?

Question

Digital certificates

Tell me what to prescribe and where?

Answer 1

Depends on what kind of server you have. Here are the redirects for nginx for example:

// https://www → https://
server {
  listen 443 ssl;
  server_name www.example.ru;

  return 301 https://example.ru$request_uri;
}
// http://www → https://
server {
  listen 80;
  server_name www.example.ru;

  return 301 https://example.ru$request_uri;
}
// http:// → https://
server {
  listen 80;
  server_name example.ru;

  return 301 https://example.ru$request_uri;
}

But it’s very good about setting up HTTPS (adding an SSL certificate and correct security settings).
