codeigniter文件夹上的htaccess支持用户登录状态

Question

I want to protect the upload-folder in my codeigniter project.

In this upload-folder is a sub-folder for every user of my project Example

uploads/user1
uploads/user2

Now I want to make sure that there is only a single way to access if the user is logged in.

So I edit with htaccess files for the upload/

# Disable directory browsing 
Options -Indexes

And for the sub-user-folders

<IfModule authz_core_module>
    Require all denied
</IfModule>
<IfModule !authz_core_module>
    Deny from all
</IfModule>

But it wont work. One time I have no access to all or at the other hand I can access all...

Is it possible to know, what I'm doing wrong or is there a better way to do?

Thanks a lot.
