Description: An interceptor in web development is a service that allows intercepting and modifying HTTP requests and responses before they are processed by the application. This mechanism is essential for managing communication between the client and the server, as it provides a centralized point to implement additional logic, such as authentication, error handling, or modifying the data being sent and received. Interceptors are commonly part of HTTP clients in various frameworks and are implemented as classes that comply with an interceptor interface. By using interceptors, developers can add custom headers, handle error responses uniformly, and perform logging or tracking tasks for requests. This ability to intercept and modify the flow of HTTP data not only improves code organization but also allows for greater reuse and maintenance of business logic related to network communications. In summary, interceptors are a powerful tool in web development that enables developers to have more granular control over HTTP interactions, facilitating the creation of more robust and secure applications.
