- Entity Headers: Provide information about the body of the resource, like its content type or length.
Importance of HTTP Headers
HTTP headers play a crucial role in:
- Security: Implementing security policies like Content Security Policy (CSP) and HTTP Strict Transport Security (HSTS).
- Performance: Managing caching mechanisms to optimize load times.
