There was a problem hiding this comment.
strings.cut is covered with existing tests but strconv.Quote is new behavior and it does not seem to have tests in this PR. It would be good to document this behavior with tests.
Tests cover: - Default realm quoting - Custom realm with spaces - Special characters (quotes, backslashes) - Empty realm fallback to default - Unicode realm support Addresses review feedback about testing strconv.Quote behavior in WWW-Authenticate header per RFC 7617 compliance. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
Move strconv.Quote(config.Realm) from per-request execution to middleware initialization for better performance. - Pre-compute quoted realm at middleware creation time - Avoids repeated string operations on every auth failure - Maintains same behavior with better efficiency Performance improvement suggested during code review. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
