 This program uses a convenience method,
 `getString()`,
 provided by the HttpRequest class
 to request the file from the server.
 
 ![Use the getString() function to make a request](images/getstringfunction.png)
 
 The getString() method uses a Future object to handle the request.
 You can use the code above as an idiom
 and provide your own code for the body of the processString() function

 ##Using an HttpRequest object to load a file {#making-a-get-request}
 
 The getString() method is good for an HTTP GET request that returns 
 a string loaded from the resource.
 For different cases,
 you need to create an HttpRequest object,
 configure its header and other information,
 and use the `send()` method to make the request.

 ###Setting up the HttpRequest object
 
 The mouse-click handler for the button
 creates an HttpRequest object,
 configures it with a URI and callback function,
 and then sends the request.
 Let's take a look at the Dart code:

 [Get Input from a Form](/docs/tutorials/forms/),
 contains a client/server example that
 shows you how to use a form to get data from the user,
 and using JSON, send that form to a server,
 and handle the server's response.
