Your HTTP headers
HTTP (Hypertext Transfer Protocol) headers are the core part of the HTTP requests and responses that is transmitted between your browser and the server. These headers, carrying important metadata, allow the client and server to pass additional information with an HTTP request or response.
HTTP headers can be categorized into two major types: Request headers and Response headers.
- Request Headers: Contain more information about the resource to be fetched, or about the client making the request.
- Response Headers: Hold additional information about the response, like its location or about the server providing it.
