About User Agents
What is a User Agent? A user agent string identifies your browser, operating system, and device to websites. It's sent with every HTTP request.
Why it matters: Websites use user agents for responsive design, compatibility checks, analytics, and content personalization.
Privacy considerations: User agents can be used for fingerprinting. Modern browsers are reducing detailed information for privacy.
Common uses: Testing websites across different browsers, debugging compatibility issues, and understanding user environments.
