title: ionic: No 'Access-Control-Allow-Origin' header is present on the requested resource
body: <p>This is my ionic.project to allow Cross Origin Request that I found after research</p>
  
  <pre><code>{
    "name": "AppName",
    "app_id": "",
    "proxies": [
      {
        "path": "/path",
        "proxyUrl": "http://www.url.com/path"
      }
    ]
  }
  </code></pre>
  
  <p>When I run ionic serve on my cmd terminal, it launches the browser and I get this on the console</p>
  
  <pre><code>XMLHttpRequest cannot load http://www.url.com/Token. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8100' is therefore not allowed access.
  </code></pre>
  
  <p>What could be wrong?</p>
