title: ob_start difference between https and http?
body: <p>Is there a different behaviour for ob_start, ob_end_flush, ob_end and ob_flush in https compared to http?</p>
  
  <p>I have read the posts about difference between http and https:</p>

  <p>as I have read this one about ob_start &amp; headers: </p>
  
  <p><a href="https://stackoverflow.com/questions/9245706/showing-error-pages-when-sending-header-with-header-function">Showing error pages when sending header with header() function</a></p>
  
  <p>but I do not find the answer I need.</p>
  
  <p><strong>My Case:</strong></p>
  
  <p>I am flushing a loading image with ob_start on two websites.
  They are using the exact same code.
  The only difference is the protocol - one is http and one is https.</p>
  
  <p><strong>The http one acts fine</strong> </p>
  
  <p>The site using <strong>http</strong> outputs the image and will then continue with the script. </p>
  
  <p><strong>The https one acts different</strong> </p>
  
  <p>The site using <strong>https</strong> outputs the image always after the script has been completely processed. </p>
  
  <p>Thanks. I am glad for any hint.</p>
