Cache status

Cache Status allows you to check, in real time, the caching behavior of a URL across the entire edge server network. It provides server-by-server visibility into whether a piece of content is being served from cache, has expired, or has never been stored.

How to analyze a URL?

At the top of the section is the Analyze URL form, made up of three fields:

Protocol: Dropdown selector to choose https:// or http://.

Domain: Dropdown selector with the domains available for the active account/service (e.g. example.com).

Path: Free text field to enter the path of the content to analyze (/path/to/content).

Next to the fields there are two buttons:

Reset: returns to the initial state to perform a new analysis.

Check Cache status: runs the cache status query.

The URL entered must be publicly accessible from the internet for the analysis to complete successfully.

Results summary

After running the analysis, five aggregated indicators are displayed:

Indicator	Meaning
Total Servers	Total number of edge servers queried.
Cache Hits	Number of servers that served the content directly from cache.
Cache Misses	Number of servers where the content was not in cache or was not valid.
Cache Pass	Number of servers that bypassed the cache (non-cacheable content, or configured in pass mode).
Cache Coverage	Percentage of data requests or overall traffic that is served and resolved by a cache.

Per-server detail

Below the summary, a list appears showing the individual status of each edge server. Each card shows:

• Result: cache result status for that server. Possible values:

  • HIT – the content was served from cache.

  • MISS – the content was not found in cache or was not fresh.

  • PASS – the request bypassed the cache.

• Ttl Remaining Time: remaining time-to-live (TTL) of the object in cache.

• Grace Remaining Time: remaining time of the grace period, during which an expired object can still be served while it is revalidated in the background.

• Keep Remaining Time: remaining time the object will be kept stored even after it has expired (useful for serving stale content in case of origin failures).

• Age Time: time elapsed since the object was stored in cache.

• Http Status: HTTP response code returned by the cached object.

• Is Stale: indicates whether the object is expired (stale) but still present in cache.

• Vary: determines how to match the headers of future requests to decide whether a cached response can be used instead of requesting a new one from the origin server.

• Hits On Object: number of times the object has been served from that server.

• Hfp: internal hash fingerprint identifier of the object in cache.
