Request rules
Shape how incoming traffic is routed to your app at the edge.
Request rules let you control how the platform's edge router handles traffic to your app — beyond the default "route the domain to the app".
What request rules do
Requests to your app first hit the edge router, which terminates TLS and decides where to send each request. Request rules let you influence that decision, for example to match specific paths or adjust how traffic is forwarded.
When to use them
- Routing different paths in a single app.
- Adjusting how the edge forwards requests to your service.
- Fine-tuning behaviour for a custom domain.
For most apps you won't need to touch request rules — the default routing (domain → app, with automatic SSL) is enough. Reach for them when you have specific routing needs.
