title: html/js: go back to previous page in the same scroll position
body: <p>Let's just say I have a page that is quite long, like an article. There's a link like <code>buy full article now</code> or something. When clicked it will redirect to a page that contains all my script, add the article to the database, and redirect back again to the article page. Is this possible? and also, how can I make it that it will redirect to same <em>scroll position</em> that the user was browsing?</p>
  
  <p><strong>Good example</strong> of this is like the <code>BACK</code> button on the browser. It will take you to the previous page you visited, at the same <em>scrolling position</em></p>
