I have a project in php created with laravel, when I identify myself and go to another page (whatever it is) and I give the browser button to go back, I skip an "expired document" 
If you are navigating between the pages, 3, 4, 5 ..... and you hit the button, you will go to the previous page, UNTIL the previous one is the one of the beginning.
I need that when you gave it back I detected that it is the start and stay in the main administrator because if you are connected I will not return to the Login ...
How can it be done?
