Frequently Asked Questions
What are HTTP headers?
HTTP headers are metadata sent with every web request, including your browser type, language preferences, encoding, and cookies. They help servers tailor responses but can reveal private information.
Can headers reveal my identity?
Yes. Headers like User-Agent and Accept-Language create a fingerprint that can identify you across sites. Use a VPN or privacy browser to minimize exposure.
How can I control my headers?
Use browser extensions like ModHeader, developer tools, or privacy-focused browsers like Tor to modify or minimize the headers you send.
