Your code can use the tokens sent by History management system to determine what kind of action you want to take. Suppose you are at page1 and that page is identified by the token 'page1'. Now, you move to page2. If you click the back button, you will receive the token 'page1'. You can use this to set the state related to page1. See this Google doc for more info.
