#454 Referer header is not sent
On clicking a hyperlink or submitting a form, 'Referer' HTTP header should be sent.
To test it, you have to use pages hosted in web container. Second page prints 'null' using HtmlUnit, and prints 'page1.jsp' URL using browser.
link1.jsp
<head>
Second Page
link2.jsp
<head>
<%System.out.println(request.getHeader( "referer" ) );%>
Code:
String url = "http://server/webapp/link1.jsp"; WebClient client = new WebClient(); CollectingAlertHandler collectingAlertHandler = new CollectingAlertHandler(); client.setAlertHandler( collectingAlertHandler ); HtmlPage page1 = (HtmlPage)client.getPage( url ); HtmlPage page2 = (HtmlPage)page1.getAnchorByHref("link2.jsp" ).click();

Attached is a patch for HtmlAnchor, and HtmlForm
To test the difference, you need a web container:
link1.jsp
<head>
<form method="post" action="link2.jsp" name="myForm">
<input type="submit" value="Second Page" name="hello">
</form>
<%System.out.println("link1.jsp: " + request.getHeader( "referer" ) );%>
link2.jsp
<head>
Third Page
<%System.out.println("link2.jsp: " + request.getHeader( "referer" ) );%>
link3.jsp
<head>
<%System.out.println("link3.jsp: " + request.getHeader( "referer" ) );%>
Code:
String url = "http://hostname/webapp/link1.jsp";
WebClient client = new WebClient();
CollectingAlertHandler collectingAlertHandler = new CollectingAlertHandler();
client.setAlertHandler( collectingAlertHandler );
HtmlPage page1 = (HtmlPage)client.getPage( url );
HtmlPage page2 = (HtmlPage)page1.getFormByName( "myForm" ).getInputByName( "hello" ).click();
HtmlPage page3 = (HtmlPage)page2.getAnchorByHref("link3.jsp" ) .click();

The current way to test such things in htmlunit unit tests is to use a MockConnection and to ask it about the header used to perform the last request.
What about following cases:
- frameset: I guess that frames should be requested with the frameset as referer
- window.open: if I correctly remember, FF sets the page where the script loads as referer whereas IE doesn't set any referer

You are absolutely right regarding frameset and window.open.
Attached is the patch.

nearly perfect but I still have one question: what does HtmlPage.getOriginatingUrl() bring compared to HtmlPage.getWebResponse().getUrl()?

Patch applied. Thanks.
I've simplified a bit the change in WebClient and added some "final" keywords.
