How can I redirect in Controller?

I have the same problem on CI v4.0.0rc3.

My .env file is configured as follow.

Code:

app.baseURL = 'http://localhost/path/'

My controller calls the following function.

PHP Code:

return redirect()->to('catalog'); 


I'm redirected to http://localhost/catalog instead of http://localhost/path/catalog.

How do I fix it?
Thanks.
