title: Callback function on domain, but redirect to localhost
body: <p>We send a request to a third party server. That server returns it to our domain, such as: <code>https://www.ourdomain.com/callbacks/script.php</code></p>
  
  <p>We then process the response. However, we are still testing. How can we have the callback push to our localhost for development? Currently the only solution we can come up with is writing a script on localhost to pull the response from our domain.</p>
