HTTP headers

HTTP headers definition

HTTP headers are a type of information that is sent between a client (such as a web browser) and a server (such as a web server) when requesting and responding to web pages. HTTP headers contain a variety of information about the client, the server, and the request or response, including the type and version of the HTTP protocol being used, the type and size of the content being transmitted, and the status of the request or response.

HTTP header location

HTTP headers are typically included in the header of an HTTP request or response message. They are used to provide additional information about the request or response, and to control how the request or response is handled.

Types of HTTP headers

There are a number of different HTTP headers[1] that can be used, including:

  • Accept: This header specifies the types of content that the client is able to understand and accept.
  • Content-Type: This header specifies the media type of the content being transmitted.
  • Cache-Control: This header specifies the caching policies for the content being transmitted.
  • User-Agent: This header specifies the client software and version being used to make the request.

HTTP headers are an important part of the HTTP protocol, as they allow for the transfer of additional information and the control of how requests and responses are handled.
