"@apollo/experimental-nextjs-app-support makes sure that we only instance the Apollo Client once per request, since Apollo Client’s cache is designed with a single user in mind, we recommend that your Next.js server instantiates a new cache for each SSR request, rather than reusing the same long-lived instance for multiple users’ data."

can someone elaborate on what this means exactly
