Description: Request headers are essential components of HTTP requests that allow clients and servers to exchange information effectively. These headers are key-value pairs that provide details about the request being made, such as the type of content being sent, authentication credentials, language preferences, and other relevant metadata. As part of the HTTP protocol, request headers play a crucial role in communication between clients (such as web browsers) and servers, facilitating content delivery and session management. Each header has a specific purpose and can influence how the server processes the request and responds to the client. For example, the ‘Content-Type’ header indicates the type of data being sent, while ‘Authorization’ is used to send access credentials. Proper use of these headers is essential to ensure smooth and secure interactions in modern web applications, especially in environments where sensitive data is handled or authentication is required.
