HtmlUnit modify outgoing request? how?

Question

I'm trying to modify a request made by HtmlUnit before it gets sent out, I did a lot of Googling and found this in their FAQ

http://htmlunit.sourceforge.net/faq.html#HowToModifyRequestOrResponse

How to modify the outgoing request or incoming response? You can subclass HttpWebConnection and override getResponse() as:

    new WebConnectionWrapper(webClient) {

        public WebResponse getResponse(WebRequest request) throws IOException {
            WebResponse response = super.getResponse(request);
            // modify the response by creating a new WebResponse
            return response;
        }
    };

I'm trying to modify the request after clicking a submit button like the example below

page = submitButtonSend.click();

How should this be written so I can modify the outgoing request before it gets sent out?

Answer 1

public WebResponse getResponse(WebRequest request) throws IOException {
    modifyRequest(request);
    return super.getResponse(request);
}
