title: html add meta tag to header after page loaded
body: <p>I want to dynamically add a meta tag to my html header after the page is loaded. I found some solutions to add a meta tag, but the all only work while the page is loading. After the page is loaded once, the dont work anymore.</p>
  <pre><code>document.head.innerHTML += '&lt;meta content=&quot;test&quot; property=&quot;test&quot;/&gt;';
  </code></pre>
  <p>Thats what I tried. But as sayed above this does not work is the page is already loaded.</p>
  <p>Is there a solution for this? Maybe something like reload the page?</p>
