Firing unnecessary API endpoint, on homepage.

[nhwaani]

As we scroll down to fetch previous posts, say at some point, we open some question to read the info in it, then we go back to homepage, as we reach homepage API is hit, refreshing all the data , thus removing the track i.e on which question the user was before pushing detail question page. Thus he needs to scroll n hit API again to fetch older pages , and this will happen to all previous questions.

Suggestion: As we scroll down to get older questions, then at sometime (unknown) say user clicks the detail page, after coming back from this page, there should be no API call to server, i.e when user clicks back button, there should be API call only if user edited ,added, deleted any resource .
For the rest cases no API must be fired.
