    <SCRIPT language="JavaScript1.2">
    function poponload()
        var url='http://localhost:8080/test/';  
        testwindow= (url);


    <form method="GET" action="test.jsp" onsubmit="javascript:poponload()">

        <input type="submit"

      You can get the url parsing the response and send a new request to the url extracted.



      include "Snoopy.class.php";
      $snoopy = new Snoopy;
      $response = $snoopy->results;

      preg_match("#var url\=\'(.*?)\'\;#", $response, $url_extracted);

      $snoopy->fetch( $url_extracted[1] );
      $content_of_file = $snoopy->results;

      header('Content-type: application/zip');
      header('Content-Disposition: attachment; filename="'.date("Ymd").'.zip"');
      print $content_of_file;


      Do you understand ?

      Good lucky

        I should have provided more details.
        What I'm really trying to do is creating a shell job which everyday downloads the zip file from a site. The path to the file (http://localhost:8080/test/ is actually created on the fly by javascript when the user presses the download button. So the content of the page does not contain the file path/name . So I can't parse the page looking for the url.

    Take a look at the javascript.  It may be in a separate file, but you can download that as well.   All the data the javascript uses is available to you as well, so it should not be too difficult to replicate whatever the javascript does.  It is possible that the javascript code itself changes as well, but that is very unlikely.
