如何获取包含 HtmlUnit 错误的网页？

Question

我正在尝试使用 HtmlUnit 2.15 API 在我的 Java 程序中访问此 Ajax page，但尝试时失败获取页面。我认为原因是对位于here 的这个损坏/丢失的file 的网站请求。

我的代码：

public class HtmlUnitExample {
    public static void main(String[] args) throws Exception, FailingHttpStatusCodeException, MalformedURLException, IOException, InterruptedException {
        WebClient webClient = new WebClient(BrowserVersion.FIREFOX_24);
        webClient.getOptions().setTimeout(120000);
        webClient.waitForBackgroundJavaScript(60000);
        webClient.getOptions().setRedirectEnabled(true);
        webClient.getOptions().setJavaScriptEnabled(true);
        webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
        webClient.getOptions().setThrowExceptionOnScriptError(false);
        webClient.getOptions().setCssEnabled(true);
        webClient.getOptions().setUseInsecureSSL(true);
        webClient.getOptions().setDoNotTrackEnabled(true);
        webClient.setAjaxController(new NicelyResynchronizingAjaxController());
        String url = "http://www.santanderuniversidades.com.br/JuriPopular/index.aspx?idprojeto=16";
        final HtmlPage page = (HtmlPage) webClient.getPage(url); //Fails here
        System.out.println(page.asXml());

    }
}

错误信息：

css的页面链接：

<link href='/JuriPopular/App_Themes/estilo/css.axd?files=jPages.css,estilo.css,jquery.fancybox.css' type='text/css' rel='stylesheet' />

调用缺失字体的cssfile：

@font-face{font-family:'DigitalDotRoadsign';
src:url('fonts/DigitalDotRoadsign.eot');
src:url('fonts/DigitalDotRoadsign.eot?#iefix') format('embedded-opentype'),
url('fonts/DigitalDotRoadsign.woff') format('woff'), //call missing file
url('fonts/DigitalDotRoadsign.ttf') format('truetype'),
url('fonts/DigitalDotRoadsign.svg#svgDigitalDotRoadsign') format('svg');
font-weight:normal;
}

这是我问题的根源吗？如果是这样的话，有没有办法避免呢？也许忽略/消除问题的原因？

实际上，为了解决这个问题，我只是启用了 cookie。我想有必要加载页面。

代码：

webClient.getCookieManager().setCookiesEnabled(true);
