title: How to open/use a url having non-standard port within an html iframe?
body: <p>I am not able to view webpage having the url: <code>http://www.example.com:9999</code> from <code>&lt;iframe&gt;</code> element, which contain a non-standard port 9999.<br><br>
  And this url (<code>http://www.example.com:9999</code>) is accessible from the browser.
  <br>
  <br>Following is the sample html code that I am using:
  <br /></p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
      &lt;title&gt;Iframe test&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
      &lt;div&gt;
          &lt;iframe src="http://www.example.com:9999" frameborder="0" height="100%" width="100%"&gt;&lt;/iframe&gt;
      &lt;/div&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p><br> 
  But when I am trying to use url having standard port(like: 80) in the <code>src</code> attribute <code>&lt;iframe&gt;</code>, that works perfectly<br></p>
  
  <p>So is there any way to use an url having non-standard port in the <code>src</code> attribute of a <code>&lt;iframe&gt;</code>.</p>
