I'm working on a project where I need to provide URL endpoints for another cloud application (Autodesk Forge), and I'm not sure how best to do this. I don't know how to provide proper access to the URL. As a test, I've created a APP Root folder for public access, and edited my web.config file with a MIME statement, thinking that if I can't download the files by openly navigating to them in a browser, then Autodesk wouldn't be able to get to them either. Currently, I can get to the folder, but when clicking the file, I get a 404.3 error. What I don't understand is why a .zip file sitting next to it can be found, without a MIME reference in the web.config file. Is that because the MIME statement doesn't play a part in describing the file, or do I have the statement entered wrong? I can fix a bad statement, but is it pointless? Second, at some point, I don't want public access to these files. Would that require I provide a signed URL to Autodesk? Or is there an easier way short of going the public route? Thank you.
