AWS AmazonS3 documentation change

Service: AmazonS3 · 2025-11-22 · Documentation low

File: AmazonS3/latest/userguide/directory-bucket-high-performance.md

Summary

Updated multiple documentation URLs by adding an extra slash after the domain name (e.g., changed 'https://docs.aws.amazon.com/' to 'https://docs.aws.amazon.com//') in links throughout the file.

Security assessment

The changes are purely cosmetic URL formatting updates with no security implications. All modifications involve adding an extra slash in documentation links, which doesn't affect authentication mechanisms (like SigV4 mentioned in the file), security controls, or vulnerability disclosures. The signature version 4 reference remains unchanged in content.
