7 Cloudflare Worker Routing Strategies Explained

1. Round Robin

Equal distribution. Stateless APIs, equal servers.

2. Weighted Round Robin

Proportional by weight. Mixed capacities, rollouts.

3. IP Hash

Consistent by IP. Cache warming, no cookies.

4. Sticky Sessions

Cookie-based. Shopping carts, logins.

5. Weighted Sticky

Capacity + persistence. Stateful + mixed.

6. Failover

Primary → backup. DR, HA.

7. Geo-Steering

By location. GDPR, latency.
