Hello

I have made a small php/mysql system which are linked to from my drupal page. I was wonder if it is possible/difficult to make sure that only users/usergroups which are logged in to my page can access this php page. It is a complete stand alone project, which does not share any templates or anything with my drupal page.

I was thinking maybe checking some session variables in my php script, but I have not been able to figure out how. Any ideas/solutions?

Thanks,

Frank
