AWS cli documentation change

Service: cli · 2025-05-25 · Documentation medium

File: cli/v1/userguide/cli_elastic-load-balancing-v2_code_examples.md

Summary

Modified ELB v2 code examples: corrected action formatting, added ARN/port details, improved redirect configuration syntax, and enhanced certificate change example

Security assessment

The changes demonstrate security best practices by: 1) Using HTTPS in redirect configurations (preventing plaintext redirects) 2) Showing proper certificate management 3) Adding security-related parameters like StatusCode=HTTP_302. While these improve security documentation, there's no evidence of addressing a specific reported vulnerability.
