From Comments:

This script leverages the fact that browsers consider whatever comes after the "#" sign in the URL as part of the browsing history. What it does is this: When the page loads, "#1" is added to the URL. After 50ms the "1" is removed. When the user clicks "back", the browser changes the URL back to what it was before the "1" was removed, BUT - it's the same web page, so the browser doesn't need to reload the page. – Yossi Shasho
