<p>how to store uploaded files in secure folder and it can be accessed securely in asp.net core? I knew the folder must be outside for www root folder. However, I did some google search still cannot find an  example. Can someone please help me give an example or give me instructions how to setup? Thanks.</p>

<p>I refer to the instructions from (<a href="http://126kr.com/article/6yo92s7gi29" rel="nofollow">Serving Static Files Outside of wwwroot in Asp.NET Core 1.0</a>) to setup. 
But it's still available for public access. I would like to only authorized user can access the uploaded files. how to do that? Thanks.</p>
