So I've been experimenting with the idea but I'm having trouble with the idea of storing documents in the web root. The ../ in the public_html/ doesn't seem to get you to another folder in the web root.
This has the link <a href="../testsecure/success.html">Test it here</a> which, if we're storing the files in a folder called /testsecure/ in the root directory, you'd have to get to those files with a link to download like that. I've created that page in the root directory, but the ../ doesn't seem to get you to the root, you remain in the public_html/ directory.
Is this the right line of thinking and if so what am I missing?
