Writing CGI Scripts

You can use Ruby to write CGI scripts quite easily. To have a Ruby script generate HTML output, all you need is

#!/usr/bin/env ruby
print "HTTP/1.0 200 OK\r\n"
print "Content-type: text/html\r\n\r\n"
print "<html><body>Hello World!</body></html>\r\n"

You could use Ruby's regular expression features to parse incoming query strings, look up environment variables, check tags, substitute text into templates, escape special characters, format up the HTML, and print it all out.

Or, you could use class CGI.
