Designed for TYPO3 13.4+ with the `redirects` system extension. The Problem ----------- [](#the-problem) TYPO3's default `RedirectService` queries and evaluates all redirects on every request. This works fine for small sets but becomes a bottleneck at scale. How It Works ------------ [](#how-it-works) Redirect matching flows through three layers, each falling back to the next on a miss: 1. **Per-request result cache** — database-backed cache keyed by `(host, path, query)`, TTL up to 24 hours. Avoids repeated matching for frequently-hit URLs. 2. **PHP file cache** — redirect data is compiled into PHP files in `var/cache/code/better_redirects/` that are loaded and optimized by OPcache. Redirects are grouped by match type and organized into trie or hash structures for fast lookup. Files are sharded automatically when a type exceeds the threshold (default: 1,000 entries per type). 3. **TYPO3's default `RedirectService`** — fallback if the PHP file cache is unavailable or cold. Cache invalidation is automatic: when a redirect record is saved or deleted via the TYPO3 backend, the result cache entries and the PHP file cache for that host are flushed immediately. Important Notes --------------- [](#important-notes) > **The extension is active as soon as it is installed.** No configuration is required. > **TYPO3's built-in redirect cache (`RedirectCacheService`) is superseded** by the PHP file cache and effectively becomes irrelevant. The built-in cache is still rebuilt on redirect changes (because the extension subclasses `RedirectCacheService`), but redirect matching never reaches it under normal operation. > **The extension aliases `RedirectService` and `RedirectCacheService`** to its own subclasses via Symfony DI. Any code that injects these classes by their concrete TYPO3 type will transparently receive the caching variants. Installation ------------ [](#installation) ``` composer require a9f/typo3-better-redirects ``` Activate the extension in the TYPO3 Extension Manager or via: ``` bin/typo3 extension:activate better_redirects ``` No additional configuration is required. The PHP file cache is populated automatically on the first request after installation (or after a cache flush). Configuration ------------- [](#configuration) One optional setting is available via `$GLOBALS['TYPO3_CONF_VARS']`: KeyDefaultDescription`EXTENSIONS/better_redirects/splitThreshold``1000`Number of redirects per match-type bucket above which the generated PHP file is split into shardsSet it in `config/system/additional.php` (or equivalent): ``` $GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['better_redirects']['splitThreshold'] = 500; ``` Requirements ------------ [](#requirements) - TYPO3 13.4 - `typo3/cms-redirects` system extension - PHP 8.2+ - OPcache recommended (the PHP file cache provides no benefit without it) ### Health Score 36 — LowBetter than 79% of packages Maintenance90 Actively maintained with recent releases Popularity18 Limited adoption so far Community6 Small or concentrated contributor base Maturity25 Early-stage or recently created project Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
