Is name set in cgi
<![CDATA[
<html>
<head><title>Test Form</title></head>
<body>
I like Ruby because:
<form target="cgibin/survey.rb">
<input type="checkbox" name="reason" value="flexible" />
It's flexible<br />
<input type="checkbox" name="reason" value="transparent" />
It's transparent<br />
<input type="checkbox" name="reason" value="perlish" />
It's like Perl<br />
<input type="checkbox" name="reason" value="fun" />
It's fun
<p>
Your name: <input type="text" name="name">
</p>
<input type="submit"/>
</form>
</body>

# survey.rb
require 'cgi'
cgi = CGI.new
cgi.has_key?('name') # true
cgi.has_key?('age') # false
