// Server API makes it possible to hook into various parts of Gridsome
// on server-side and add custom data to the GraphQL data layer.
// Learn more: https://gridsome.org/docs/server-api/

// Changes here require a server restart.
// To restart press CTRL + C in terminal and run `gridsome develop`

module.exports = function (api) {
  // Set specific response HTTP headers for JSON files only:
  //
  // - max-age = 0     : the response is never fresh
  //
  // - s-maxage = 0    : the response is never fresh in a shared cache
  //                     (e.g. Proxy, CDN…)
  //
  // - no-cache        : the response can be stored in caches, but the response
  //                     must be validated with the origin server before each
  //                     reuse, even when the cache is disconnected from the
  //                     origin server.
  //
  // - must-revalidate : the response can be stored in caches and can be reused
  //                     while fresh (never here). If the response becomes stale
  //                     (straighaway here), it must be validated with the
  //                     origin server before reuse.
  //
  // - proxy-revalidate: equivalent of must-revalidate, but for shared caches
  //
