Use "global.php" without updating lasactivity and lastvisit

[belinea]

I want to use some vBulletin functions in my own PHP Script. So i have included the global.php in my script. But when my script become executed Vbulletin refreshes the user.lastactivity and user.lastvisit informations in the databse. Is there a way to prevent this? I want to use vBulletin functions but vBulletin shouldn´t regocnizes me as an visitor in the forum.

Many many thanks for some hints.
