TechTrade Cache Warmer — keep every page fast, no hosting cron needed

TechTrade Cache Warmer keeps every page of your CS-Cart store fast by regularly re-loading all sitemap URLs in the background, so template, database and opcode caches never cool down and the first visitor never hits a cold, slow page. No hosting cron, no server access, no code changes.

Without a reverse-proxy cache, PHP renders every page live and internal caches expire between visits, so the unlucky first visitor gets the slow render. This add-on fixes exactly that, powered by a WordPress-style pseudo-cron that runs off your normal visitor traffic.

Key features:

- Fully automatic: warm-up every 1/2/4/6/12/24 hours, triggered by visitor traffic, with no cron job to configure.

- Works with any sitemap: file patterns in the web root (sitemap*.xml) and/or absolute sitemap URLs; sitemap index files are resolved automatically.

- Parallel warming (2/4/8 connections) with a lock against double runs.

- Near-zero overhead: the triggering visitor is delayed at most about 0.5 s; every handler is wrapped defensively, so the add-on can never break a request.

- Status endpoint with last run, result and a log of the last 100 runs.

- Clean: no database tables, no theme or core changes; uninstall leaves nothing behind.

Requirements: CS-Cart / Multi-Vendor 4.20+, PHP cURL, and a sitemap (built-in generator or any SEO add-on).

Built and proven in daily use on our own marketplace, warming 1,500+ pages every hour. Support comes straight from the developers.
