title: Creating a Secure File Hosting Server for PDFs
body: <p>I'm working to develop a website that allows clients to log in and see various <code>PDFs</code> saved on the server.  These PDFs will be unique to the client and should not be accessible by someone who is not logged in.  Getting the files onto the server shouldn't be an issue, I'm just not sure on how to serve them to end users.</p>
  
  <p>I've implemented this kind of thing with data from <code>SQL servers</code> being served instead of files, so I'm not entirely sure what the most effective way to go about this.</p>
  
  <p>The website is on a <code>LAMP</code> and my minimal experience is in <code>PHP</code> (but if a framework or other language would make this easier, I can learn it).</p>
  
  <p>I'm probably in over my head but I usually am, so any input would be great.</p>
