Common Questions
What are HTTP Headers?
They are the core part of HTTP requests and responses, carrying metadata about the browser, the requested page, the server, and more.
Why are security headers important?
Headers like HSTS and CSP tell the browser how to behave securely, preventing attacks like Cross-Site Scripting (XSS) and Clickjacking.
