title: redirect to login page while downloading a file via absolute url classic asp
body: <p>I have a private area in my website in which I put some files (mostly archives) to download. Only registered users can download those files. 
  The files are uploaded into the folder /writable/public/... so as right now if someone writes on the address bar www.mysite.com/writable/public/..., this person can actually download the file. What I'd like to obtain is to redirect this attempt to my login page in ASP classic.
  I've read about HTTPHandlers but for what I've understood they work for ASP.NET and I don't know how to use them in ASP classic.</p>
