AWS elasticloadbalancing documentation change

Service: elasticloadbalancing · 2025-10-16 · Documentation low

File: elasticloadbalancing/latest/application/edit-rule.md

Summary

Added documentation about 'transforms' capability in ALB listener rules alongside existing actions/conditions. Updated references to include transforms in rule management steps, CLI commands, and CloudFormation instructions.

Security assessment

The changes introduce 'transforms' as a new configurable aspect of ALB rules but provide no specific security context. While header transforms could theoretically be used for security purposes (e.g., security headers), the diff contains no explicit references to security implementations, vulnerabilities, or security-specific features. This appears to be a general feature expansion rather than security-focused documentation.
