Logical. You load the page, which automatically gets reloaded, thus creating a new entry in the history. Now when you go back, you land on the page with window.location.reload() and the same happens again.

now the question: why are you doing this? I see no reason for window.location.reload() on pageload.

You could use:

if(history.length) {
  window.location.reload();
}

A much better option though if your page must not be cached, would be to set the appropriate cache-control and expires headers, examples of which can be found at http://www.web-caching.com/mnot_tutorial/how.html
