/isr-cache-headers/Vercel STALE Cache Demo
- This example tests cache STALE for time-revalidated ISR pages.
- The /isr-cache-headers/timestamp is an ISR page with a 15s revalidation period.
- It takes 5 seconds to create a new snapshot of the page.
- During those 5 seconds, the STALE (previously cached) content is returned.
- Click on the Start Fetching button, to send 20 consecutive requests inspecting the corresponding cache headers and timestamp content values.
