Only Logged in user can access folder/file using Owin

Question

Hi,

I'm stuck here how can do it. Please help me.  I'm describing in steps

 

I'm using Owin for registration and log in. 

 

 Step 1-

I have created a web Application in ASP.NET MVC just for User register and login.

 

Step 2- 

I have written some codes in registration that my code will create a folder by username which are going to register. 

 

Step 3-

Suppose Two users registered in our application and stored data into database which name is User1 and User2.

 

Step 3-

There are two folders created under root folder.

Suppose a root folder is UserFiles  

• UserFiles/User1
• UserFiles/User2

Step 4-

I have added user1.pdf under User1 folder.

Same as for another user user2.pdf under User2 folder.

 

Step 5-

Direct URL to access these pdf will be:

 

http://localhost:9022/UserFiles/User1/user1.pdf

 

http://localhost:9022/UserFiles/User2/user2.pdf 

 

Step 6-

The main requirement is here now:

Suppose User1 is logged in then User1 can access only own folder like below-

http://localhost:9022/UserFiles/User1/user1.pdf 

 

And also when without logged in user is hitting these URL then our system will prompt and ask for log in and redirect in our login page.
