History.state is always null when using appcache

[SatishGandham]

Earlier I used to use history.state to decide if an user can go back any further in the application.
But after enabling appcache, it's always null. Is there a workaround or alternate way to know if the user can goback ?

Does it have something to do with hash paths?

Example use case:
Consider there is a blog app
User clicks a link to a post (I love IronRouter), the link opens in the app.
User then follows this path
I love IronRouter > post author > home > I love IronRouter .

Now when the user goes back, he has to goto home > post author > I lover iron router

At this stage, backbutton won't be displayed.
