How to post HEAD request with HtmlUnit?

How can I use existing WebClient to post a custom HEAD request? I.e. there is no开发者_如何学Python form on the page, I want to set request properties manually.

Use WebClient#getPage() where you pass the WebRequestSettings in which you can construct with a HttpMethod of HEAD.

Thus, basically:

Page page = webClient.getPage(new WebRequestSettings(new URL("http://stackoverflow.com"), HttpMethod.HEAD));
