title: Is stdWrap.cache still working in v7.6/8.7?
body: <p>Tried to use stdWrap.cache on different instances (TYPO3 7.6.23 and 8.7.8) according to <a href="https://docs.typo3.org/typo3cms/TyposcriptReference/7.6/Functions/Cache/" rel="nofollow noreferrer">https://docs.typo3.org/typo3cms/TyposcriptReference/7.6/Functions/Cache/</a> But the content is rendered for each page instead of sharing it with other pages. </p>
  
  <p>Also the exact example doesn't work:</p>
  
  <pre><code>page = PAGE
  page.5 = TEXT
  page.5 {
    stdWrap.cache.key = mycurrenttimestamp
    stdWrap.cache.tags = tag_a,tag_b,tag_c
    stdWrap.cache.lifetime = 3600
    stdWrap.data = date : U
    stdWrap.strftime = %H:%M:%S
  }
  </code></pre>
  
  <p>Can anybody confirm this? Or does anybody currently have a working usecase?</p>
