What types of HTTP headers do you know?

HTTP headers are key-value pairs transmitted in HTTP requests and responses to pass additional information.

Main types of headers:

• Request headers: contain information about the client and the request.

  • Host — the domain name of the server.
  • User-Agent — information about the browser or client.
  • Accept — data types that the client is willing to accept.
  • Authorization — authentication data.

• Response headers: contain information about the server and the response.

  • Content-Type — the content type.
  • Content-Length — the length of the content.
  • Set-Cookie — setting cookies.
  • Server — information about the server.

• General headers: applicable to both requests and responses.

  • Cache-Control — cache management.
  • Connection — connection management (e.g., keep-alive).

• Entity headers: describe the message body.

  • Content-Encoding — encoding method of the content.
  • Content-Language — language of the content.

These headers help manage the behavior of HTTP messages and facilitate metadata exchange between the client and server.
