Problem with www to non-www redirect

I'm currently using apache as server and I stock with this kind of redirect. When user is going to **www.site.com** he must be forwarded to **site.com**
My .htaccess looks like this

```
RewriteCond %{HTTP_HOST} !^site.com$ [NC]
RewriteRule ^(.*)$ http://site.com/$1 [L,R=301]
```

And it works when I turn off the node server. But when server is on it looks like the express is forwarding requests by itself.

Also investigated that demo isn't redirecting. **https://www.react-redux.herokuapp.com/** won't work.
