Paste the Cookie header and the formatter splits each cookie into readable key-value lines.
HttpOnly helps prevent client-side scripts from reading the cookie, reducing some XSS risks.
Secure tells browsers to send the cookie only over HTTPS connections.
SameSite controls whether cookies are sent with cross-site requests and helps reduce CSRF risk.
Copy the Cookie header, paste it into the formatter, and review each key-value pair separately.
