Interface EdgeCacheOptions

Allows you to force caching of responses marked as private in their cache-control header. This option must be used with utmost care to avoid leaking private information.

Example

 import { Router, CustomCacheKey } from '@edgio/core/router'

 new Router()
   .match('/private/path', ({ cache }) => {
     cache({
       edge: {
         maxAgeSeconds: 60 * 60,
         key: new CustomCacheKey()
           .addCookie('session'),
         forcePrivateCaching: true,
       }
     })
   })

The maximum number of seconds (or Saifish time interval) that a response is served from the cache until it is considered stale. Unless staleWhileRevalidate is specified, stale responses will not be returned to the browser.

Extends the duration that a response will be served from the cache after it has become stale. When using staleWhileRevalidate, if Edgio receives a request for a stale asset, the cached response will be served and a fresh response will be concurrently fetch so that it can be served for future requests. The stale response will continue to be served until the fresh fetched.
