[Htmlunit-user] How to identify if page gets refreshed and how to wait for it

[David M. G. <mic...@gm...>]

Hi all,

For the following link:

http://www.scielo.org.co/scielo.php?script=sci_arttext&pid=S0120-99572012000600002
I want to get the address of the pdf.
When pressing on the pdf link with the text "Article in pdf format" i get
to a refresh page.
How do i know that i am now in a refresh page and how many seconds i will
wait?
Alternatively, how can i get the pdf link without waiting.

I tried to find a solution on my own
I wanted somehow to parse the redirect page source and get the following
tag (which you get with view source):
<meta name="added" content="7;URL=
http://www.scielo.org.co/pdf/rcg/v27s2/v27s2a02.pdf" http-equiv="refresh">

When trying to make the same with htmlunit:
public static void main(String[] args) throws
FailingHttpStatusCodeException, MalformedURLException, IOException {
        WebClient webClient = new WebClient();
        List<String> urls = ImmutableList.of("
http://www.scielo.org.co/scielo.php?script=sci_arttext&pid=S0120-99572012000600002
");
        for(String url:urls) {
            HtmlPage page = webClient.getPage(url);
            List<HtmlAnchor> anchors = page.getAnchors();
            for (HtmlAnchor anchor:anchors) {
                String linkText = anchor.getTextContent();
                if(linkText.contains("pdf")) {
                    Page pdfPage = anchor.click();
                    if(pdfPage.isHtmlPage()) {
                        HtmlPage p = (HtmlPage) pdfPage;
                        System.out.println(p.asXml());
                    }
                }
            }
        }

    }
I don't get this tag in the resulting xml.

In summary i have the following questions:
How do i know that i am now in a refresh page and how many seconds i will
wait?
After identifying that i am in a refresh page, how do i wait and refresh
after this number of seconds?
how can i get the pdf link without waiting.
Where did the <meta name="added" content="7;URL=
http://www.scielo.org.co/pdf/rcg/v27s2/v27s2a02.pdf" http-equiv="refresh">
tag disappear?

Thanks,
David
