Need help for KCFinder


I am using KCFinder application to upload files, images using CKFinder. But my problem is i can’t configure session for KCFinder. Now i am facing problem that any public user can access KCFinder uploader by writing the location of KCFinder (if he/she knows the location). But it should be accessible only by master admin and that’s why it needs to configure session.

I have followed the link:

But this is not clear to me. Need further explanation with example to clear my concept. If anyone know about this please help me.

Thank You,
