Is it possible to find out the address of the page from which the request was made to the server without passing it?

Question

Node.js

The front on the SSR is deployed on port 3000, and the server is on port 4000.
Is it possible to find out the full address of the page from which the request was made?

Now I can only get the host:

origin: 'http://localhost:3000',
referer: 'http://localhost:3000/',
