/**
 * HTTP request initializer.
 *
 * For example, this might be used to disable request timeouts:
 *
 * 
 * public class DisableTimeout implements HttpRequestInitializer {
 * public void initialize(HttpRequest request) {
 * request.setConnectTimeout(0);
 * request.setReadTimeout(0);
 * }
 * }
 * 
 *
 * Sample usage with a request factory:
 *
 * 
 * public static HttpRequestFactory createRequestFactory(HttpTransport transport) {
 * return transport.createRequestFactory(new DisableTimeout());
 * }
 * 
 *
 * More complex usage example:
 *
 * 
 * public static HttpRequestFactory createRequestFactory2(HttpTransport transport) {
 * final DisableTimeout disableTimeout = new DisableTimeout();
 * return transport.createRequestFactory(new HttpRequestInitializer() {
 * public void initialize(HttpRequest request) {
 * disableTimeout.initialize(request);
 * }
 * });
 * }
 * 
 *
 * Implementations should normally be thread-safe.
