Cache effectiveness

When Peakhour processes a browser request, several outcomes can occur: - proxied - rewritten - cached - blocked

Proxied means that the cache responded to the request by passing it to the origin.

Rewritten from origin means that the request was optimised by Pagespeed.

Cached means the response was served from the cache.

Blocked means the request was blocked by the security layer.

Several of these outcomes may be combined, for example proxied, rewritten means the request was proxied from the origin and rewritten by pagspeed.

To optimise performance, the goal is the increase the amount of cached responses served by Peakhour.

Reviewing cache performance

We have several analytic graphs that can assist you to discover both your cache hit rate and possible quick wins.

hits by type "Hits by type"

This graph shows a high percentage of cached traffic and a low percentage of proxied traffic.

top proxied requests "Top proxied requests"

This graph shows the top URLS being proxied to your origin server. You can use this graph and its drilldown to help locate URLs that require overriding caching behaviours.
