User-Agent Reference Guide

  • Browser Identification: Client applications send the User-Agent HTTP header to inform servers about their application name, version, and host operating system.
  • Legacy & Modern Contexts: Due to historical browser spoofing (e.g., embedding "Mozilla", "KHTML", "Safari", and "Chrome" strings together), modern parsers use pattern matching heuristics to identify accurate environments.
  • Feature Detection: Whenever possible, rely on modern JavaScript feature detection rather than rigid User-Agent string parsing for production web logic.
