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

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.

Answer 1

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

Answer 2

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.
