How do you clear the Open Graph cache of an URL on Telegram?
<p>When I send a new link on Telegram, it automatically reads <a href="http://ogp.me/" rel="noreferrer">Open Graph</a> data of the URL and generates a preview of the page.</p>

<p>When the Open Graph data of the same page changes, though, Telegram doesn't update its preview: it has cached the old Open Graph data!</p>

<p>How do you clear the Open Graph cache?</p>

<h3>Preview Example:</h3>

<p>For the URL <code>https://asp.net/</code> Telegram is reading the following tags:  </p>

<pre><code>&lt;meta property="og:site_name" content="Microsoft"&gt;
&lt;meta property="og:title" content="ASP.NET | Open-source web framework for .NET"&gt;
&lt;meta name="twitter:image" content="https://dotnet.microsoft.com/images/redesign/social/large.png"&gt;
&lt;meta property="og:description" content="ASP.NET is a free web framework for building great Web sites and Web applications using HTML, CSS and JavaScript." /&gt;
</code></pre>

<p>And is generating the following preview:</p>

<p><a href="https://i.stack.imgur.com/H8V5y.png" rel="noreferrer"><img src="https://i.stack.imgur.com/H8V5y.png" alt="enter image description here"></a></p>
