Hi,
In a different, but similar problem: I have tried logging all visitors to my site, using a stand-alone script.
I call this script from the page I want to log, through an include:
require(script.php ..) with a specific identiefier, to tell the script what to do (?action=loguser).
This returns the text: 'You are user number ** for today' to the original page (Part of the script).
If you can edit the script on your compagny server you should be able to work it this way.
