 /**
- * A client-side XHR request for getting data from a URL,
- * formally known as XMLHttpRequest.
+ * A utility for retrieving data from a URL.
  *
- * HttpRequest can be used to obtain data from HTTP and FTP protocols,
- * and is useful for AJAX-style page updates.
+ * HttpRequest can be used to obtain data from http, ftp, and file
+ * protocols.
  *
- * The simplest way to get the contents of a text file, such as a
- * JSON-formatted file, is with [getString].
- * For example, the following code gets the contents of a JSON file
- * and prints its length:
+ * For example, suppose we're developing these API docs, and we
+ * wish to retrieve the HTML of the top-level page and print it out.
+ * The easiest way to do that would be:
  *
- *     var path = 'myData.json';
- *     HttpRequest.getString(path)
- *         .then((String fileContents) {
- *           print(fileContents.length);
- *         })
- *         .catchError((Error error) {
- *           print(error.toString());
- *         });
- *
- * ## Fetching data from other servers
+ *     HttpRequest.getString('http://api.dartlang.org').then((response) {
+ *       print(response);
+ *     });
  *
- * For security reasons, browsers impose restrictions on requests
- * made by embedded apps.
- * With the default behavior of this class,
- * the code making the request must be served from the same origin
- * (domain name, port, and application layer protocol)
- * as the requested resource.
- * In the example above, the myData.json file must be co-located with the
- * app that uses it.
- * You might be able to
- * [get around this restriction](http://www.dartlang.org/articles/json-web-service/#a-note-on-cors-and-httprequest)
- * by using CORS headers or JSONP.
+ * **Important**: With the default behavior of this class, your
+ * code making the request should be served from the same origin (domain name,
+ * port, and application layer protocol) as the URL you are trying to access
+ * with HttpRequest. However, there are ways to
+ * [get around this restriction](http://www.dartlang.org/articles/json-web-service/#note-on-jsonp).
  *
- * ## Other documentation
+ * See also:
  *
- * * [Fetch Data Dynamically](https://www.dartlang.org/docs/tutorials/fetchdata/),
- * a tutorial from _A Game of Darts_,
- * shows two different ways to use HttpRequest to get a JSON file.
- * * [Get Input from a Form](https://www.dartlang.org/docs/tutorials/forms/),
- * another tutorial from _A Game of Darts_,
- * shows using HttpRequest with a custom server.
