How to set up multiple domains name on the same project

I have deployed my dynamic website module on Vercel. I use React and Supabase. The URLs have the following format: Site 1: https://web4all.vercel.app/1/home Site 1: https://web4all.vercel.app/1/contact Site 1: https://web4all.vercel.app/1/personalizePage

Site 2: https://web4all.vercel.app/2/home Site 3: https://web4all.vercel.app/3/home

I would like to configure my domain names for each site so that I can access them with these URLs: domainName1/home domainName1/contact domainName1/personalize

domainName2/home domainName3/home"

however it seems i can not add a redirection toward vercel.app/1 for example. I'm sure someone already tried to do it but i did'nt find anything yet.

Hi Pawlean,

thanks for your answer ! I'm afraid the post you're bringing used a different technologie. I'm not sure i could apply those solutions on my problem ☹️
