So I have a sedcondary domain (secondary.domain.com) that is being redirected to my applications primary domain (app.domain.com). This is configured in the domains section of the vercel project (where this next app is deployed).

My goal is to be able to not redirect directly to app.domain.com, but rather app.domain.com/sign-up?param=1.

A - is this possible?
B - what is the recommended approach for this? I would imagine from the docs that the middleware file could help, but I'm not sure if that is handled before or after vercel redirects the domain.

FYI - this project uses the latest version of Next, using the app directory
