## HTTP Headers Demystified
HTTP headers allow clients and servers to pass additional metadata with requests and responses.
### Essential Headers
1. **Content-Type**: Specifies the media type of the resource (e.g. `application/json`, `text/html`).
2. **Cache-Control**: Directs how resources should be cached (e.g. `no-cache`, `max-age=3600`).
3. **Authorization**: Contains credentials for authenticating a client with a server (e.g. `Bearer `).
4. **Strict-Transport-Security (HSTS)**: Forces connections to use HTTPS for enhanced communication security.
