[TYPO3] no caching for php in templates

[a owen]

hi

i'm including php-scripts with typo=script like this: 
  subparts.menu = PHP_SCRIPT
  subparts.menu.file = fileadmin/php/menu.php
  
unfortunately they are cached but i need them to be executed every time.
i know about the extension lumonet and i'm using it. is there a setting
to prevent a subpart chaching in a template or do i have to include it
with lumonet?

thanks
andi
