VergeCloud’s X-Cache and X-Time Headers Explained

VergeCloud’s X-Cache and X-Time Headers Explained

Once VergeCloud's CDN service is activated, the system includes the x-cache and x-time headers in the responses to user requests.

What Does X-Cache Mean?

The x-cache header can have several possible values: MISS, HIT, and BYPASS.

  • MISS: The requested content isn't available in VergeCloud’s servers and is fetched directly from the website's origin server. This is typically the case for the first request made by the user from any VergeCloud PoP.
  • HIT: The content is cached on VergeCloud’s servers, and the user is receiving this cached content.
  • BYPASS: The requested content will never be cached by VergeCloud servers and will always be served directly from the website’s origin server.

If the x-cache value reads BYPASS but you want it to be cached, you can configure the page settings in the Special Rules section of the VergeCloud panel.

What Does X-Time Mean?

The x-time header shows the response time.

  • If x-cache is MISS or BYPASS, the x-time represents the response time from the origin server to VergeCloud's servers.
  • If x-cache is HIT, the x-time shows the response time from VergeCloud's servers to the user.
