title: URL name not changing
body: <p>I hope that it's okay to ask this question here. As a complete beginner i was wondering how some websites url addresses don't change when you click on an internal link. So if for example the url is www.mysite.com it remain exactly that if you clicked on the "contact" link of that site for example. Also when i go to my site it changes to www.mysite.com/home.html but some other site remain www.mysite.com.</p>
  
  <p>Thanks for any help
