About HTTP Headers
What are HTTP Headers?
HTTP headers are key-value pairs sent by a server in response to an HTTP request. They provide metadata about the response and instructions to the client.
Security Headers
Headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security help protect websites from attacks and vulnerabilities.
Performance Headers
Headers like Cache-Control, ETag, and Content-Encoding help optimize website performance through caching and compression.
