Cloudflare Edge Dynamic Redirect Engine & Webhook Ingestion Cluster

Handling 2.4M monthly requests at 14ms global latency with zero origin server strain.

Cloudflare Workers Cloudflare KV TypeScript n8n Webhooks k6 Load Testing

[ 01 // THE CORE PROBLEM ]

A hospitality group running 18 property websites merged their domains into a single primary brand. They faced 25,000 legacy URLs requiring 301 redirection that immediately overloaded their origin servers.

[ 02 // THE CHALLENGE ]

Migrating 25,000 URL redirection mappings with query string preservation, geo-specific currency routing, and live CRM webhook intake without adding latency or hosting infrastructure costs.

[ 03 // VERIFIED OUTCOME ]

Average redirect latency dropped from 840ms to 14ms. Origin server CPU utilization dropped from 92% to 11%, saving over $1,400 monthly in dedicated cloud server scaling costs.

[ INVESTIGATION & FORENSICS ]

Origin Apache server rewrite rules created memory exhaustion spikes and 504 Gateway Timeouts under high crawl concurrency from search engine indexers.

[ SYSTEM ARCHITECTURE BLUEPRINT ]

Cloudflare Workers cluster with distributed Cloudflare KV storage. Ingestion layer using asynchronous Cloudflare Queues to buffer CRM reservation webhooks before pushing to internal Postgres database.

[ ENGINEERING IMPLEMENTATION ]

Engineered a TypeScript Cloudflare Worker utilizing prefix-tree and KV lookups for sub-millisecond route matching. Built an automated n8n pipeline allowing non-technical marketing managers to update redirect rules via Google Sheets sync directly into KV.

[ RIGOROUS VALIDATION PROTOCOL ]

Load tested using k6 at 5,000 requests per second across 12 global cloud regions. Verified 100% preservation of UTM parameters and referrer headers.

Project Context

A hospitality brand consolidating 18 boutique hotel websites under a single domain needed to protect over a decade of earned organic SEO equity.

The Technical Problem

25,000 unique URLs with complex regex query patterns.
Apache .htaccess rewrite files exceeded 4MB in size, causing every HTTP hit to re-parse the rewrite tree.
Booking confirmation webhooks from external OTAs (Expedia, Booking.com) frequently overwhelmed the booking database during seasonal campaigns.
