In this session you will:

parse form data
use cgi-lib.pl

POST

ssh into emperor.mousetrap.net
go to your virtual webserver's directory
review the logs in your logs directory.
make a new CGI application, called day1post.cgi. The application should:

- print out which browser (user agent) the user has.
run it from the command line
run it from the browser.
view the html source from your browser.
debug as needed. When you've got it running, leave the results in your browser for proof.
