Automatic redirect question - Point me in the right direction...

I've a site that doesn't need to be password protected, but management would like to gather information regarding who is using and downloading information.

I'd like to be able to redirect someone to a survey/form if they have not already filled it out anytime they try to go further than the home page, and once they've filled out the form/survey, be sent on to the requested page.

I've a general understanding of html tags and layout, but not much more depth in adding script to html. I do have background in C++ and Visual Basic however, so I believe I can get through if I know where to start.

Websites or tutorials or just a general nudge would be extremely helpful.

Regards,

Kurt R. Kowitz
