class
A final HttpHandler which will dispatch the request via browser HTTP APIs to a backend.
abstract class HttpBackend implements HttpHandler {
abstract handle(req: HttpRequest<any>): Observable<HttpEvent<any>>
} Interceptors sit between the HttpClient interface and the HttpBackend.
When injected, HttpBackend dispatches requests directly to the backend, without going through the interceptor chain.
