Instant Cloudflare Cache Invalidation for High-Traffic WordPress
RelayWP injects Cache-Tag
headers so Cloudflare can purge every linked page — article, category, author, feed — in a single
API call. Publish a story and every related page is fresh at the edge in under a second.
Your readers see stale headlines
minutes after you publish
Every article update affects dozens of pages — category listings, author feeds, related sections, sitemaps. Clearing them one-by-one just can't keep up.
Without RelayWP
One update.
Dozens of stale pages.
Plugins that clear cache URL by URL send a separate request for every affected page. On a busy news site that can mean 60+ seconds of readers getting outdated content while the queue drains.
- 1 You publish an article update
- 2 Plugin loops through every affected URL
- 3 Each URL is cleared one by one
- 4 Rate limits kick in, queue backs up
- 5 Content is stale for up to 60 seconds
With RelayWP
One update.
Every page fresh instantly.
RelayWP tags every page with its relationships at serve time. When you publish, a single signal clears the article, its category, its author page, related feeds — all at once, across Cloudflare's entire global edge.
- 1 You publish an article update
- 2 RelayWP identifies all related pages by tag
- 3 One request clears every affected page simultaneously
- 4 Cloudflare propagates the purge globally
- 5 Readers get fresh content in under a second

Cloudflare Free
through Enterprise
Everything you need
Tag injection, page builder & ACF support, exclusion rules, real-time diagnostics, one-click CF setup — plus Pro tiers with analytics, scheduling, multilingual purge, and CI/CD deploy webhooks.
Automatic Cache-Tag Injection
RelayWP writes a Cache-Tag header on every public WordPress response — posts, archives, author pages, feeds, and more — so Cloudflare always knows exactly what to invalidate.
Edge Purge in Under a Second
One API call clears every tagged page at Cloudflare's edge simultaneously. RelayWP then pre-warms freshly purged pages so the first real visitor always gets a CDN hit, not a cold origin request.
Cascading Linked-Page Invalidation
One post save purges the article, every assigned category, the author archive, tag pages, RSS feeds, and sitemaps — all simultaneously. Nothing stale slips through.
Works on All Cloudflare Plans
Cache-tag purging is available on Free, Pro, Business, and Enterprise — not just Enterprise. RelayWP also falls back to URL-based purging automatically if needed, so every site is covered.
Cache Status Checker
Enter any URL to see its live CF-Cache-Status, get a plain-English diagnosis of why it's not caching, and receive a list of suggested fixes — all without leaving WordPress admin.
One-Click Cloudflare Setup
RelayWP auto-creates the required Cloudflare Cache Rule for you — no dashboard, no YAML, no Terraform. One click and HTML caching is live across the entire zone.
WooCommerce Integration
Stock changes, price updates, and order status events precisely purge product pages, category listings, and related caches — without touching unrelated pages.
WP-CLI Commands
Full command-line control: purge by post, URL, tag, or zone. AI tools like Claude Code and Cursor run WP-CLI — add one command to flush the exact pages they just changed.
External Webhook API
Bearer-token REST endpoint AI agents can call directly — no WordPress session. Works from n8n, Make, Zapier, GitHub Actions, Vercel, Netlify, or any HTTP-capable script.
Cache Exclusion Rules
Exclude URLs by pattern, cookie name, or query parameter from receiving Cache-Tag headers — keeps admin sessions, preview links, and cart pages from ever being cached.
Page Builder & ACF Support
Elementor, Beaver Builder, Bricks, and Advanced Custom Fields all trigger cache purges natively — even when they bypass the standard save_post hook.
Purge Analytics Dashboard
Track total purges, success rate, average duration, daily trends, and top triggers — all inside WordPress admin. Pull live Cloudflare hit-rate and bandwidth data too.
Multilingual Purge
Polylang and WPML translation sets are detected automatically — updating a source post or term purges every translated variant at the same time.
Scheduled Purges & Deploy Hooks
Queue a full-zone or targeted flush for any future time. Or use the HMAC-signed deploy webhook so your CI/CD pipeline flushes exactly the right pages at the end of every deploy.
Works with every AI tool that touches WordPress
AI coding agents — Claude Code, Cursor, GitHub Copilot, Windsurf, Devin — interact with WordPress via WP‑CLI commands and REST API calls, not the admin UI. When they create or update content, the cache never hears about it.
RelayWP closes that gap. One CLI command or one HTTP call from inside your agent's workflow flushes exactly the right pages, immediately.
# AI agent finishes updating post ID 42
wp relaywp purge post 42
# → clears post, categories, author, feed, sitemap
# Or wipe everything after a bulk import

Frequently asked questions
- Which Cloudflare plans support cache-tag purging?
- All of them — Free, Pro, Business, and Enterprise. Cache-tag purging is available across every Cloudflare plan. The difference is rate limits: Free allows 5 tag-purge requests per minute; Enterprise allows 50 per second. RelayWP works efficiently within those limits on any plan.
- How does the annual subscription work?
- You are billed once a year. Your license stays active as long as your subscription is active — cancel any time from your account dashboard, no questions asked.
- What happens when I cancel?
- The plugin keeps working on your site. You lose access to updates and support until you renew, but nothing breaks.
- What payment methods are accepted?
- Credit/debit card, UPI, and net banking via Razorpay. Prices shown in USD.
- What's your refund policy?
- 30-day money-back guarantee, no questions asked.
- Does the free plugin require RelayWP Pro?
- No. The free plugin is fully functional on its own — tag injection, purge, page builder & ACF support, cache exclusion rules, dry-run mode, and settings import/export are all included at no cost. Pro adds WooCommerce, multilingual purge, analytics, Cloudflare zone analytics, scheduling, failure notifications, the deploy webhook, WP-CLI commands, and the DB-backed queue.
Built for sites that publish, not just host
Whether you run a news desk, a magazine, or a high-volume WooCommerce store — if stale content costs you readers or conversions, RelayWP keeps your edge cache accurate at every publish. Get started free, upgrade when you need analytics, scheduling, multilingual purge, failure notifications, or CI/CD deploy webhooks.
