i have a question about using res.setHeader, for ssr cache management. here is the code

res.setHeader(
    'Cache-Control',
    'public, s-maxage=864000, stale-while-revalidate=300'
  )

my question is
- is the s-maxage is too much & is this cause issues like an user who previously visited a page, wont be able to see the updated content?

love to know your opinions & suggestions
