Depending on your setup that can be dozens of pages with news plugins that are flushed when a news record is edited, for example. This extension detects URLs of pages that have fallen out of the cache and provides a scheduler task to warm them up automatically, before your visitors have to do it. Installation ------------ [](#installation) `composer require smic/page-warmup` Usage ----- [](#usage) After installing the extension, set up a new scheduler task with the class "Page Cache Warmup Queue Worker (page\_warmup)". The recommended (conservative) setup is: - Type: Recurring - Frequency: 120 - Don't Allow Parallel Execution - Time limit in seconds: 60 That's it. Whenever the caching framework flushes page caches based on cache tags, the affected pages will automatically get warmed up again. [![Scheduler Task](doc/scheduler.png?raw=true "Scheduler Task")](doc/scheduler.png?raw=true) If the cache warmup is too slow, you can try a more aggressive setup like: - Type: Recurring - Frequency: 60 - Allow Parallel Execution - Time limit in seconds: 240 That will result in ~ 4 simultaneous task processes, that are working on the queue. That means increased load on your system. Under the hood -------------- [](#under-the-hood) In the TYPO3 caching framework entries are flushed by tags or all at once, and it gives you no feedback about what content / information has actually been flushed - that makes it hard to know what needs warming up. That's why this extension collects that information when a page is cached. It remembers the URLs and cache tags in a so called *warmup reservation*. When a cache tag is flushed, the extension can pull up all reservations matching that tag, and write the page URLs to a warmup queue. ### Detecting when a page is cached [](#detecting-when-a-page-is-cached) TYPO3 doesn't have a suitable hook or middleware to react to pages being cached, so this Extension provides a cache `VariableFrontendWithWarmupReservation` and registers it for the `pages` cache. It takes a look at all incoming cache entries and what *looks* like the cache entry for a page, will be written into a warmup reservation. ### Health Score 48 — FairBetter than 93% of packages Maintenance79 Regular maintenance activity Popularity33 Limited adoption so far Community13 Small or concentrated contributor base Maturity56 Maturing project, gaining track record Bus Factor1 Top contributor holds 83.8% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
