use drupal_add_js for file outside drupal dir I would like to add a js file thats outside my drupal installation dir, but keep it relative to that dir.

mysite
  |-- drupal
  |-- dirWithJsFile
      |-- thisfile.js


i have already tried things like 

/../dirWithJsFile/thisfile.js
../dirWithJsFile/thisfile.js


but add_js seems not be able to go outside the drupal dir or is there an option i must set?
In D6, no dice, but in D7, you could fudge it with setting $options to external and then using the full sitename and path to the file.
