After upgrading to DNN 6, I've noticed that the Hyperlink Manager in the HTML editor is no longer generating secure links with the LinkClick function. Instead it is simply creating relative links using direct URLs. Before the upgrade to DNN 6, I was using the FCKeditor provider; after the upgrade I'm using the RadEditor option because the FCKeditor did not work for me in DNN 6.
Normally the direct URL link would be fine (if not even preferred), but I have several PDF files whose direct URLs need to be kept hidden, lest my unscrupulous users send those URLs to other, unauthorized users. The LinkClick feature prevented this, because it forced users through an authentication routine. The PDFs remained freely available at their respective URLs, but nobody knew what those URLs were.
So, my question is in two parts: one, how do I get LinkClick to work again in my HTML editor for DNN 6? More than that, though, I'd like to know if LinkClick is the best practice for truly securing PDFs or other resources in DNN, so that only authorized users have access to them? The LinkClick method is only effective as long as nobody has the direct URL to the file, but security by obscurity is only so effective. Is there a better method I should know about?
Thanks in advance!
