What is the best way to manage returning to the original page that was loaded when utilizing the History API?

I'm in a bit of a pickle here. I've been using History.js with the History API and everything was going smoothly until I encountered an issue. Let's start with a simple page setup like this:

<div ="header">
  Header
</div>
<div id="content">
  Content
</div>
<div id="footer">
  Footer
</div>

My AJAX calls involve replacing the content of #content with new HTML, but the problem arises when a user navigates back to the initial page. It attempts to load the entire first page again, resulting in something like this:

<div ="header">
  Header
</div>
<div id="content">
  <div ="header">
    Header
  </div>
  <div id="content">
    Content
  </div>
  <div id="footer">
    Footer
  </div>
</div>
<div id="footer">
  Footer
</div>

I know there must be a better way to structure my page to avoid this mess, but I can't seem to figure it out. Here's the code snippet I'm currently using:

(function(window,undefined){
    var
    History = window.History,
    State = History.getState();

    History.Adapter.bind(window,'statechange',function(){
    var State = History.getState();
    $.ajax({
        url: History.getState().url,
        cache: false
    }).done(function( html ) {
        $("#content").html(html);
    });
    });
})(window);

If you have any insights on how to tackle this issue properly, I'd greatly appreciate it!

<?php

    $check_ajax = isset( $_SERVER['HTTP_X_REQUESTED_WITH'] ) && ( $_SERVER['HTTP_X_REQUESTED_WITH'] == 'XMLHttpRequest' );

    if ( $check_ajax ) {
      // Provide the requested content
    } else {
      // Display a complete webpage
    }

?>
