     * The primary public API included in `HTTP_PROVIDERS` is the {@link Http} class.

     *
     * The providers included in `HTTP_PROVIDERS` include:
     *  * {@link Http}
     *  * {@link XHRBackend}
     *  * {@link XSRFStrategy} - Bound to {@link CookieXSRFStrategy} class (see below)
     *  * `BrowserXHR` - Private factory to create `XMLHttpRequest` instances
     *  * {@link RequestOptions} - Bound to {@link BaseRequestOptions} class
     *  * {@link ResponseOptions} - Bound to {@link BaseResponseOptions} class
     *
     * There may be cases where it makes sense to extend the base request options,
     * such as to add a search string to be appended to all URLs.
     * To accomplish this, a new provider for {@link RequestOptions} should
     * be added in the same injector as `HTTP_PROVIDERS`.
     *
     * ### Example ([live demo](http://plnkr.co/edit/aCMEXi?p=preview))
     *
     * ```
     * import {provide} from '@angular/core';
     * import {bootstrap} from '@angular/platform-browser/browser';
     * import {HTTP_PROVIDERS, BaseRequestOptions, RequestOptions} from '@angular/http';

     *
     * bootstrap(App, [HTTP_PROVIDERS, {provide: RequestOptions, useClass: MyOptions}])
     *   .catch(err => console.error(err));
     * ```
     *
     * Likewise, to use a mock backend for unit tests, the {@link XHRBackend}
     * provider should be bound to {@link MockBackend}.
     *
     * ### Example ([live demo](http://plnkr.co/edit/7LWALD?p=preview))
     *
     * ```
     * import {provide} from '@angular/core';
     * import {bootstrap} from '@angular/platform-browser/browser';
     * import {HTTP_PROVIDERS, Http, Response, XHRBackend} from '@angular/http';
     * import {MockBackend} from '@angular/http/testing';
     *
     * var people = [{name: 'Jeff'}, {name: 'Tobias'}];
     *
     * var injector = Injector.resolveAndCreate([
     *   HTTP_PROVIDERS,
     *   MockBackend,
     *   {provide: XHRBackend, useExisting: MockBackend}
     * ]);
     * var http = injector.get(Http);
     * var backend = injector.get(MockBackend);
     *
     * // Listen for any new requests
     * backend.connections.observer({
     *   next: connection => {
     *     var response = new Response({body: people});
     *     setTimeout(() => {
     *       // Send a response to the request
     *       connection.mockRespond(response);
     *     });
     *   }
     * });
     *
     * http.get('people.json').observer({
     *   next: res => {
     *     // Response came from mock backend
     *     console.log('first person', res.json()[0].name);
     *   }
     * });
     * ```
     *
     * `XSRFStrategy` allows customizing how the application protects itself against Cross Site Request
     * Forgery (XSRF) attacks. By default, Angular will look for a cookie called `'XSRF-TOKEN'`, and set
     * an HTTP request header called `'X-XSRF-TOKEN'` with the value of the cookie on each request,
     * allowing the server side to validate that the request comes from its own front end.
     *
     * Applications can override the names used by configuring a different `XSRFStrategy` instance. Most
     * commonly, applications will configure a `CookieXSRFStrategy` with different cookie or header
     * names, but if needed, they can supply a completely custom implementation.
     *
     * See the security documentation for more information.

     * bootstrap(App, [JSONP_PROVIDERS, {provide: RequestOptions, useClass: MyOptions}])
     *   .catch(err => console.error(err));
     * ```
     *
     * Likewise, to use a mock backend for unit tests, the {@link JSONPBackend}
     * provider should be bound to {@link MockBackend}.
     *
     * ### Example ([live demo](http://plnkr.co/edit/HDqZWL?p=preview))
     *
     * ```
     * import {provide, Injector} from '@angular/core';
     * import {JSONP_PROVIDERS, Jsonp, Response, JSONPBackend} from '@angular/http';
     * import {MockBackend} from '@angular/http/testing';
     *
     * var people = [{name: 'Jeff'}, {name: 'Tobias'}];
     * var injector = Injector.resolveAndCreate([
     *   JSONP_PROVIDERS,
     *   MockBackend,
     *   {provide: JSONPBackend, useExisting: MockBackend}
     * ]);
     * var jsonp = injector.get(Jsonp);
     * var backend = injector.get(MockBackend);
     *
     * // Listen for any new requests
     * backend.connections.observer({
     *   next: connection => {
     *     var response = new Response({body: people});
     *     setTimeout(() => {
     *       // Send a response to the request
     *       connection.mockRespond(response);
     *     });
     *   }
     * });

     * jsonp.get('people.json').observer({
     *   next: res => {
     *     // Response came from mock backend
     *     console.log('first person', res.json()[0].name);
     *   }
     * });
     * ```
