Amazon Web Services (AWS) announces URL and Host Header rewrite capabilities for Application Load Balancer (ALB). This feature enables customers to modify request URLs and Host Headers using regex-based pattern matching before routing requests to targets.
With URL and Host Header rewrites, you can transform URLs using regex patterns (e.g., rewrite “/api/v1/users” to “/users”), standardize URL patterns across different applications, modify Host Headers for internal service routing, remove or add URL path prefixes, and redirect legacy URL structures to new formats. This capability eliminates the need for additional proxy layers and simplifies application architectures. The feature is valuable for microservices deployments where maintaining a single external hostname while routing to different internal services is critical.
You can configure URL and Host Header rewrites through the AWS Management Console, AWS CLI, AWS SDKs, and AWS APIs. There are no additional charges for using URL and Host Header rewrites. You pay only for your use of Application Load Balancer based on Application Load Balancer pricing.
This feature is now available in all AWS commercial regions.
To learn more, visit the ALB Documentation, and the AWS Blog post on URL and Host Header rewrites with Application Load Balancer.
