title: t3blog - how to clear cache when user writes comment?
body: <p>When a user writes a comment then it doesn't become visible right away. It becomes visible if I clear the cache manually.</p>
  
  <hr>
  
  <p>Usually t3blog stores posts and comments within the t3blog page itself and then one should be able to clear the cache this way.</p>
  
  <pre><code>TCEMAIN.clearCacheCmd = all
  </code></pre>
  
  <hr>
  
  <p>However in my t3blog setup the posts and comments are in a separate sysfolder. Here is the setup typoscript</p>
  
  <pre><code>plugin.tx_t3blog_pi1.blogPid = 21
  </code></pre>

  <p><strong>Is there a way I can trigger clear cache when the user submits a new comment?</strong></p>
