CF GarageThe shortcomings of generic advice on complex edge infrastructure
Cloudflare's product architecture has evolved rapidly. Much of the guidance found across community forums is either deprecated or dangerous when applied to production stacks:
- Deprecated Page Rules guidance: Older tutorials still recommend legacy Page Rules, while Cloudflare has transitioned to dedicated suites (Cache Rules, Redirect Rules, Transform Rules, Custom WAF Rules), each evaluated independently.
- Strict evaluation pipeline ordering: Edge rules execute in a specific lifecycle sequence (DNS → SSL/TLS → Transform Rules → Redirect Rules → WAF → Rate Limiting → Cache Rules → Origin). Stacking rules haphazardly causes silent logic collisions.
- Risk of production lockouts: Misunderstanding SSL modes (Flexible vs Full Strict), triggering global "Under Attack" modes, or deploying aggressive WAF rules can instantly break checkout flows or trigger redirect loops (ERR_TOO_MANY_REDIRECTS).
- Context matters: Settings that speed up a static portfolio site will break session handling for a SaaS API or transactional shopping carts.
A disciplined, risk-free methodology
Professional Cloudflare optimization requires a structured three-step process:
- Read-only scoping (Least Privilege): Full audit of your security events, cache analytics, and rule evaluation chains without altering your active zone.
- Simulation mode verification (Log Action): New security expressions are evaluated in logging mode first, observing real traffic behavior before active enforcement.
- Precision Wirefilter rule drafting: Clean rule expressions leveraging native edge fields (
cf.client.bot, ASN classification, JA3/JA4 fingerprints, HTTP headers) for maximum performance. - Measurable satisfaction guarantee: We establish a baseline metric together before starting, backed by a full refund if no measurable improvement is achieved.
