Rewrite to a new domain? with url query? not working. :( help - apache

Question

I have this rewrite rule...
Redirect all initial request from world.example.com to web.example.com
RewriteCond %{HTTP_HOST} ^world\.example\.com$ [NC]
RewriteCond %{HTTP_HOST} !^$
RewriteCond %{SERVER_PORT} !^80$
RewriteRule ^(.*)$ https://web.example.com$1 [R=301,L]
Which works great. But, some of my applications has...
https://world.example.com/approvals/?id=b47b5256567
Unfortunately, it is not being redirected properly to web.example.com. Instead, it just goes to web.example.com without the query params.
How could I make all request redirect properly to web.example.com along with the query params?
Basically, what it should do...
https://world.example.com/approvals/?id=b47b5256567
then
https://web.example.com/approvals/?id=b47b5256567
Just changing the world to web and passing the query string.
Help

Answer 1

You don't need to use the complicated rewrite engine to do this. Just use Redirect:
<VirtualHost *>
ServerName world.example.com
Redirect permanent / https://web.example.com/
</VirtualHost>
The Redirect directive automatically preserves everything that comes after what you're redirecting.

Answer 2

You forgot to use the "Query String Append" flag [R=301,L,QSA].

Answer 3

We can do it with Nginx, too.
server {
listen 80:
server_name: world.example.com
# URL redirect
#rewrite ^ http://web.example.com$request_uri? permanent;
rewrite ^ $scheme://web.example.com$request_uri permanent;
#rewrite ^ $scheme://web.example.com permanent;
#rewrite ^ $scheme://web.example.com;
}
