Automated Cache Warming

Automated Cache Warming

Keep every important URL warm before the next visitor arrives.

Automated cache warming is the core of Cache Rocket. Instead of waiting for a real user to regenerate a cold page, Cache Rocket visits your URLs like a client—on a schedule you control—so CDNs, reverse proxies, and application caches stay hot.

Highlights

  • Schedule recurring warm cycles without cron scripts
  • Crawl entry URLs, sitemaps, and discovered links
  • Respect rate limits so origin stays healthy
  • Track status and results from a live dashboard

Why cold caches hurt

When a cache entry expires, the next request often rebuilds the full page on origin. That first hit is slow for the visitor and expensive for your servers—especially during traffic spikes, sales, or editorial publishes.

Cache Rocket removes that first-hit penalty by warming URLs ahead of demand. Your CDN or host already has a fresh response when people arrive.

How Cache Rocket warms pages

You verify a hostname you own, create a warmer with entry URLs or sitemaps, and set crawl depth, intervals, and request options. Cache Rocket then crawls like a real browser client—following links within your rules—and regenerates cache along the way.

Paid plans unlock more warmers, deeper crawls, higher throughput, and advanced options such as custom headers, cookies, and multi-region warming.

Works with the caches you already use

Cache Rocket does not replace your CDN or page cache. It complements them. Whether you use Cloudflare, Fastly, Bunny, nginx, Varnish, WordPress object/page cache, or an application-level cache, warming over HTTP keeps those layers ready.

How it works

  • Verify ownership: Confirm you control the hostname with DNS or an HTTPS verification file.
  • Configure a warmer: Add entry URLs or sitemaps, set depth, intervals, and optional headers or agents.
  • Let it run: Cache Rocket crawls on schedule and reports progress, errors, and cache health signals.

Use cases

  • Content sites & blogs: Keep new and evergreen articles warm so readers never wait on a cold publish.
  • E-commerce catalogs: Warm product grids, category pages, and campaign landing URLs before peak traffic.
  • Marketing sites: Protect conversion pages from cold TTFB during ads spikes and launches.

FAQ

Do I need to install something on my server?

No. Website warmers work over HTTP against public URLs. An optional WordPress plugin adds deeper local integration if you want it.

Will warming overload my origin?

You control max URLs per minute and crawl depth. Start conservative and raise limits as origin headroom allows.

What caches does it warm?

Any cache that regenerates when a URL is requested—CDN edge, reverse proxy, full-page cache, or app cache.
