In a request and response communication of a HTTP call if we want to inject some custom logic the HTTP Interceptor comes into picture. HTTP Interceptors executes some custom logic before or after the HTTP call. For example appending the authentication token to every HTTP request and that token is generated from the client who needs to be validated at the server for security purpose. These interceptors act as a hook up for the HTTP calls. HTTP Interceptors are used for adding custom logic for authentication authorization session/state management logging modifying Response URL rewriting Error handling Caching adding custom header timestamp in the request /response encrypt and decrypt the request and response information or manipulate the request and response data over the request cycles.
