When traffic spikes, origin-first delivery becomes the bottleneck.
Peakhour turns that bottleneck into a controlled edge path. Cache keys and rules decide hit, miss, purge, stale, and origin-shield behaviour, with evidence on every response whether Peakhour is your CDN or adds cache control beside an existing edge.
Where Cache Control Changes the Delivery Path
Origin Saturation and Cost
Cache static and dynamic routes at Peakhour Edge, or add Peakhour cache policy beside an existing CDN, with explicit keys, shielded misses, and hit/miss analytics. More responses served from cache means fewer origin requests and less infrastructure spend.
Freshness by Rule
Use purge-by-tag, ETag support, range requests, and stale-while-revalidate controls to keep pages fast without serving stale business-critical content longer than intended.
Scale with Confidence
Detailed response headers, dashboards, and log exports show hit ratio, latency, cache key decisions, purge state, and origin relief so teams can tune caching safely alongside WAF, rate limiting, and traffic-control changes.
Rules Decide the Cache Outcome
You do not have to be a programmer to configure caching. Build rules for route, device, cookie, header, query-string, and cache-tag behaviour so each response gets the right cache key and freshness policy.
Rules, purge state, and delivery evidence stay visible while Peakhour keeps unnecessary origin fetches out of the request path. The same operating view can sit on Peakhour Edge or alongside the edge you already run.
Purge and Recover Without Origin Shock
Clear content from Peakhour instantly by URL or cache tag, then track the control state as affected objects are invalidated across the edge. Combined with origin shield and miss collapse, purge controls let teams move quickly without pushing every visitor back to origin.
Teams can publish, correct, and recover quickly without forcing every visitor back to origin.

This dashboard evidence shows where caching is working and where responses still reach origin, so teams can tune cache policy, WAF, rate limits, and traffic controls with full clarity.
Debug headers, analytics, and log exports keep cache behaviour visible as traffic grows.
Deploy Full-Page Caching Across Your Stack
Peakhour provides and supports plugins for popular platforms to enable optimal full-page caching strategies. Use Peakhour as a drop-in replacement for Varnish for Magento and Drupal, or enhance your WordPress, WooCommerce, OpenCart, or PrestaShop stores.
Cache tags, purge hooks, and dynamic route rules let catalogue, article, and campaign pages stay fast while checkout, account, and API paths remain dynamic and protected. Teams can manage that caching beside WAF, rate limiting, traffic control, and origin shield policy instead of stitching separate edge tools together.
