title: Using meta refresh tag in the iframe source page causes the page to refresh where iframe has being called
body: <p>I was finding a quick way for a simple chat page, as I don't want to use Ajax or jQuery so I used the below tag on the source page like for example <code>page2.php</code></p>
  
  <pre><code>&lt;meta http-equiv="refresh" content="2"&gt;
  &lt;!--And the page content goes here--&gt;
  </code></pre>
  
  <p>And I used this on <code>page1.php</code></p>
  
  <pre><code>&lt;iframe src="page2.php" border="1"&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>Now what I expected was only <code>iframe</code> to be refreshed but the the whole <code>page1.php</code> is refreshed, why that so? Than what's the use of declaring <code>meta refresh</code> on <code>page2.php</code>? Does actually using <code>iframe</code> embeds the markup of the source page in the page where we are using the iframe?</p>
