Hi Pierre, Pierre Joye in php.windows (Tue, 9 Jul 2013 07:46:48 +0200): >impersonation should solve this problem. I've to check if another >function(s) has to be used to get the impersonated user. Please check it out. I suppose I will not be the only one interested in running multiple PHP's with OPcache on Windows, but a little background might come of help. On our Windows 2008 R2 servers we have a mixture of old Drupal6 and newer Drupal7 sites. They need to be running on Windows, because we are heavily using Windows Media Services to stream WMV-files. For instance the Views module in Drupal6 is not prepared for PHP5.4+. It runs but is generating numerous error messages. So we still need PHP 5.3 as long as we have not upgraded those sites (and that may be quite a long time from now). For our Drupal7 sites we want to switch to PHP 5.5 to benefit from the increased speed and stability. For both PHP versions we are impressed by the performance gain OPcache delivers. So there it is: how do we run PHP 5.3 with Opcache and PHP 5.5 with OPcache under the same Apache?
