title: Any security concerns from pointers in ReSTFUL URLS
body: <p>Say you have a restful URL, where you have a pointer to an important object in the URL, such as:</p>
  
  <pre><code>/api/shoppingcart/{shoppingcartid}/
  </code></pre>
  
  <p>Or </p>
  
  <pre><code>/api/creditcard/{creditcardid}/
  </code></pre>
  
  <p>Is that not very dangerous? For example, suppose a hacker sees the URL, they could just change it very easily and post on up to your site?</p>
  
  <p>If I go this approach,how can I be sure there is nothing risky going to happen?</p>
  
  <p>Thanks</p>
