  <p>I have a url that will look like</p>
  
  <p><a href="http://example.com/register" rel="nofollow">http://example.com/register</a></p>
  
  <p>I want that to hit</p>
  
  <p><a href="http://example.com/account/register/normal" rel="nofollow">http://example.com/account/register/normal</a></p>
  
  <p>I also have</p>
  
  <p><a href="http://example.com/invite/something_random_here" rel="nofollow">http://example.com/invite/something_random_here</a></p>
  
  <p>which I want to hit </p>
  
  <p><a href="http://example.com/account/register/invite/something_random_here" rel="nofollow">http://example.com/account/register/invite/something_random_here</a></p>
  
  <p>I also have</p>
  
  <p><a href="http://example.com/register/something_random_here" rel="nofollow">http://example.com/register/something_random_here</a></p>

  <p><a href="http://example.com/account/register/subscribed/something_random_here" rel="nofollow">http://example.com/account/register/subscribed/something_random_here</a></p>
