title: TYPO3 Extbase - Change browser page title in single view
body: <p>I'm trying to change the browser page title when in single view of my extbase extension. All my attempts failed:</p>
  
  <pre><code>/**
   * action show
   *
   * @param \Vendor\Abc\Domain\Model\Abc $record
   * @return void
   */
  public function showAction(\Vendor\Abc\Domain\Model\Abc $record) {
      $this-&gt;view-&gt;assign('record', $record);
  
      //$GLOBALS['TSFE']-&gt;page['title'] = $record-&gt;getAbc();
      //$GLOBALS['TSFE']-&gt;indexedDocTitle = $record-&gt;getAbc();        
  
      //$GLOBALS['TSFE']-&gt;page['title'] = $record;
      //$GLOBALS['TSFE']-&gt;indexedDocTitle = $record;  
  
      //$GLOBALS['TSFE']-&gt;additionalHeaderData['CustomUserIntTitle']
      //= '&lt;title&gt;' . $this-&gt;getAbc($record) . '&lt;/title&gt;';
  
      //$myNewTitle = 'Title';
      //$title = '&lt;title&gt;' . $myNewTitle . '&lt;/title&gt;';
      //$this-&gt;response-&gt;addAdditionalHeaderData($title);
  
      //$GLOBALS['TSFE']-&gt;content = preg_replace('#&lt;title&gt;.*&lt;\/title&gt;#', '&lt;title&gt;' . $record-&gt;getTitle() . '&lt;/title&gt;', $GLOBALS['TSFE']-&gt;content);
  
      //$this-&gt;response-&gt;addAdditionalHeaderData('&lt;title&gt;Mein eigener Title&lt;/title&gt;');
  }
  </code></pre>
  
  <p>I registred the action as non-cacheable (not sure if I really have to though) </p>
