casperjs download file without specifying url

Is there any way to download CSV file with casperjs without specifying download URL? I am trying to download CSV file whose URL is dynamically generated when I click the dow

For the record, it's already possible using 'resource.received' event. If you receive header like this one:

Content-Disposition: Attachment; Filename="ExportData.csv"

The file generated can be downloaded using following event listener:

casper.on('resource.received', function(resource) {
    if (resource.stage !== "end") {
        console.log("resource.stage !== 'end'");
        return;
    }
    if (resource.url.indexOf('ExportData.csv') > -1) {
        console.log("Downloading csv file");
        this.download(resource.url, 'ExportData.csv');
    }
});
