Applications can disable redirection via <a href="api/Request.html#followRedirects(boolean)"><code>Request.followRedirects(boolean)</code></a>

<pre>
HttpRedirector redirector = new HttpRedirector(httpClient);
Request request = httpClient.newRequest("http://host/path").followRedirects(false);
ContentResponse response = request.send();
while (redirector.isRedirect(response))
