About HTTP Headers

HTTP headers are key-value pairs sent with every web request and response. They serve several important purposes:

  • Browser information: Tell servers about your browser and system
  • Security: Implement security policies and protections
  • Content negotiation: Specify preferred languages and content types
  • Caching: Control how content is cached
Headers marked with the Security badge are important for web security
