/**
* Provides the client-side classes and interfaces for making HTTP requests and
* processing the associated responses.
*
* <p>
* Most applications will be interested in the {@link com.google.gwt.http.client.Request}, {@link com.google.gwt.http.client.RequestBuilder},
* {@link com.google.gwt.http.client.RequestCallback} and {@link com.google.gwt.http.client.Response} classes.
* </p>
*
* <h2>Caveats</h2>
* <h3>Same-Origin Security Policy</h3>
* Modern web browsers restrict client-side scripts from accessing items outside
* of their source origin. This means that a script loaded from <code>www.foo.com</code> cannot access
* content from <code>www.bar.com</code>. For more details please see, <a
* href="http://en.wikipedia.org/wiki/Same_origin_policy">Same-Origin Security
* Policy</a>.
*
* <h3>Pending Request Limit</h3>
* Modern web browsers are limited to having only two HTTP requests outstanding at
* any one time. If your server experiences an error that prevents it from sending
* a response, it can tie up your outstanding requests. If you are concerned about
* this, you can always set timeouts for the request via {@link com.google.gwt.http.client.RequestBuilder#setTimeoutMillis(int)}.
*
* <h3>Required Module</h3>
* Modules that use the classes and interfaces in this package should inherit
* the <code>com.google.gwt.http.HTTP</code> module.
*
* {@gwt.include com/google/gwt/examples/http/InheritsExample.gwt.xml}
*
* <h2>Quick Howto's</h2>
* <h3>How should I write a RequestCallback handler class?</h3>
* The following code shows how a {@link com.google.gwt.http.client.RequestCallback} instance should be written.
* {@example com.google.gwt.examples.http.client.RequestCallbackExample}
*
* <h3>How do I make a GET request?</h3>
* The following example demonstrates how to perform an HTTP GET request.
* {@example com.google.gwt.examples.http.client.GetExample}
*
* <h3>How do I make a POST request?</h3>
* The following example demonstrates how to perform an HTTP POST request.
* {@example com.google.gwt.examples.http.client.PostExample}
*
* <h3>How do I use request timeouts?</h3>
* The following example demonstrates how to use the timeout feature.
* {@example com.google.gwt.examples.http.client.TimeoutExample}
*
* <h3>How do I construct a string for use in a query or POST body?</h3>
* The following example demonstrates how to build a x-www-form-urlencoded string that can be used as a query string or as the body of a POST request.
* {@example com.google.gwt.examples.http.client.QueryAndFormDataExample}
*
* <h3>How can I make a {@link com.google.gwt.http.client.RequestBuilder} send a request other than GET or POST?</h3>
* The following example demonstrates how to allow an HTTP request other than a GET or a POST to be made. <em>Beware: if you plan on supporting Safari, you cannot use this scheme.</em>
* {@example com.google.gwt.examples.http.client.RequestBuilderForAnyHTTPMethodTypeExample}
