title: strange issue reloading webpage very slow - but fast when force-reload
body: <p>I have a strange behaviour with one of my webpages:</p>
  
  <p>When I load/reload the page, it takes ages for the TTFB (time to first byte) - sometimes up to 30 seconds.</p>
  
  <p>Interestingly, when I do a force-reload (F5/holding down SHIFT-Key) the page loads instantly (TTFB under a second).</p>
  
  <p>I tried to disable the cache-control in htaccess (I thought this might be the issue since shift-reload works fast), but it didn't help.</p>
  
  <p>The page is a typo3 installation with multiple domains - none of the other domains has the same problem.
  Also, it only happens with the homepage - all the subsequent pages load fine.</p>
  
  <p>Any ideas???</p>
