How to do "permission page" to facebook application?

Question

Could you tell me how to do? From A to Z. I have huge problem. Documentation is telling, that you have to redirect to

https://graph.facebook.com/oauth/authorize?client_id=[client_id]&redirect_uri=http://[address_page]/&scope=" + perm; 

But how to do, that page wouldn't redirect again and again? I know, that I can check login status, but to this I must FB.init.
