Missing or Insecure Cache-Control Header
Web cache or HTTP cache is a system for optimizing the web. Browsers cache contents of a resource once and reuse it on consequent requests. Caching images on the web can boost page load time. But clients should not be allowed to cache pages that display sensitive, dynamic, or user specific contents.
Set any of following headers to prevent clients from caching the page.
Cache-Control: no-cache, no-store
Cache-Control: max-age=0, must-revalidate
