EE-WBC PERL CGI Programming Examples

CGI Scripts (mostly with PERL5)

• Setting up CGI scripts on your own
• Introduction to CGI Scripts

  Test if CGI works at all	test it
  A simple CGI script	test it
  It can be done in C++ as well	test it
  CGI Counter	test it
  Again in C++	test it

• Investigating CGI Scripts and their environment

  Printing some Environment variables	test it
  Printing all Environment variables	test it
  Printing all data from the form	test it
  Log file or guest book recording	test it

• CGI Scripts interacting with HTML front end

  A sample simple HTML form submitted by GET	its source	and the test CGI script that responded
  A sample simple HTML form submitted by POST	its source	and the test CGI script that responded
  A sample simple HTML form submitted by E-MAIL,	its source
  A sample simple HTML form submitted by E-MAIL without encoding,	its source

• Pieces from real life

  Getting data from a text configuration and listing it on a web page	test it	config.txt
  A "real life" form	its source	script used this time for testing
  Processing logfile statistics	test it	tbLog.txt
  use AMCGI.pm	require errror.pl

• CGI Scripts that generate graphics, not HTML (real life use would involve plotting data acquired on the fly)

  A simple data plot

  test it
