Strategized with @balazsorban44 to open one larger PR, with changes to individual examples as separate commits. For each example, I researched how multiple realworld codebases use the featured technology with TypeScript, to thoughtfully convert them by hand - nothing automated whatsoever. ## Documentation / Examples - [X] Make sure the linting passes by running `pnpm lint` - [X] The "examples guidelines" are followed from [our contributing doc](https://github.com/vercel/next.js/blob/canary/contributing/examples/adding-examples.md) |

Server-Side Rendering Caching Headers
This example uses stale-while-revalidate cache-control headers in combination with getServerSideProps for server-rendering.
pages/index.tsx uses getServerSideProps to forward the request header to the React component, as well as setting a response header. This cache-control header uses stale-while-revalidate to cache the server response.
pages/index.tsx is considered fresh for ten seconds (s-maxage=10). If a request is repeated within the next 10 seconds, the previously cached value will still be fresh. If the request is repeated before 59 seconds, the cached value will be stale but still render (stale-while-revalidate=59).
In the background, a revalidation request will be made to populate the cache with a fresh value. If you refresh the page, you will see the new value shown.
