Ano ther application of this technique is the redirection of Web page addresses without modifying the server's configuration file. Apparently we cannot cover everything about CGI, Perl, Java, Javascript, etc in one term. I demonstrated how the CGI work with a Unix program I wrote many years ago. Event looks at a couple of databas e files and echoes important events and celebrities' birthday happening on a given date. I wrote CGI interfaces in C, C-shell, and Perl.
Student can present a form requesting month, day and year.
The form will be sent to a CGI program, which calls even t and presents the output back to the browser in HTML format. Finally, I talked a little bit about the server configuration, in particular about access authorization and directory indexing. At the end of the term, most of the students built a fancy Web site. Frankly, some of them are far better than mine. They told me that they have fun and also learned a lot in this class.
