Dynamically routing requests with Amazon API Gateway routing rules
Compute Blog
AWS API Gateway has introduced dynamic routing rules for custom domain names, enabling more flexible API request routing based on HTTP headers and URL paths.
- New routing rules allow routing decisions based on HTTP headers, base paths, or combinations of both
- Supports scenarios like API versioning, A/B testing, and gradual feature rollouts
- Routing rules have three key properties: Conditions, Actions, and Priority
- Supports header matching with exact, prefix, suffix, and wildcard conditions
- Three routing modes: API mappings only, routing rules then API mappings, and routing rules only
- Provides enhanced observability through access logging with new context variables
This feature allows developers to implement complex routing strategies without modifying API endpoints, offering more control and flexibility in API management.
