Do Not Track user preference

Read Original

This article discusses the Do Not Track (DNT) HTTP header, explaining why websites should respect user privacy by honoring this setting. It provides practical code examples for detecting DNT in JavaScript (client-side) and in server-side environments like PHP and Node.js, demonstrating how to conditionally load analytics scripts. The author argues implementation is simple and that many users with DNT enabled already block tracking, so the impact on data collection is minimal.
