This verification form uses a CGI program on the server to
see if the supplied user name and password match "jones" and
"opensesame", respectively. Try it with both incorrect and the
correct information. The only difference between this example and
that of Figure 18.6 is that the information from this form is cleaned
up and submitted to the CGI program using a hidden form. Compare the
query string sent by this example with the query string that Figure
18.6 sends.
