RouteViewer linking with RouteDownload
This is a RouteYou+ service. You can only use this is you pay for the RouteYou+ services.
Download via your website
You can also allow the download via your own website (see important remark above!) using the download widget (read here more about the download widget. This means that your user doesn't jump the website of RouteYou.
How to realize this
This is one example of how to do the trick:
Plug in the RouteViewer in page 1 of your website.
Add the following parameter to your script of the RouteViewer:
routeyou_viewer_url_download = 'http://www.yourwebsite.aspx?downloadpage';
Obviously, you should change the info : 'http://www.yourwebsite.aspx?downloadpage';
This is not the same page as page 1 (for the obvious reason that you want to show now the download info and not the RouteViewer).
