Unless cgicc has changed since I last used it, the concept of "session" is not 
part of the library.

The simplest method to track information from form to form is to use hidden 
variables in the form. In a secure application this may not be acceptable 
because when the user views the source then this hidden information is not 
hidden anymore.

Java Servlets/JSPs and MS ASP have a concept of a session implemented via 
cookies. Most commercial applications use this method. That is why all these 
sites say you must have cookies enabled to use their site. You could of course 
implement your own cookie mechanism.

There are other ways to track users but they are harder to implement in my 
opinion. Since its school, usually the hidden field mechanism gets a decent 
enough grade.
