Fix bug in getAllHeaderNames helper function where it incorrectly used 'this._headers' instead of 'res._headers'. This bug would cause the function to fail on Node.js 0.8 (the minimum supported version) because: - Node.js 0.8 doesn't have getHeaderNames() method, so it uses the fallback path that reads from _headers - Inside the function, 'this' is not the response object, so this._headers is undefined - This would cause getAllHeaderNames to always return [] even when headers exist The fix changes 'this._headers' to 'res._headers' to correctly use the response object parameter that was passed to the function. This ensures compatibility with all supported Node.js versions, including Node.js 0.8.
