<li>I can POST a URL to <code>[project_url]/api/shorturl/new</code> and I will receive a shortened URL in the JSON response.<br>Example : <code>{"original_url":"www.google.com","short_url":1}</code></li>
<li>If I pass an invalid URL that doesn't follow the <code>http(s)://www.example.com(/more/routes)</code> format, the JSON response will contain an error like <code>{"error":"invalid URL"}</code><br>
HINT: to be sure that the submitted url points to a valid site you can use the function <code>dns.lookup(host, cb)</code> from the <code>dns</code> core module.</li>
<li>When I visit the shortened URL, it will redirect me to my original link.</li>
