Also try to explain the following:

• basic overview of chapter 11 in the text (three important sections)

Full transformation of a simple program (week of Oct. 13-15):

• same program in php with hidden fields
• same program converted to CGI/Perl with hidden fields
• table for the program converted to CGI/Perl with sessions in MySQL
• same program converted to CGI/Perl with server-side state in sessions stored in MySQL

The enumeration above almost entirely summarizes our class, for this semester.
