Personally, I don't quite like the CGI#out style of doing things so I set
the headers myself then output the html my own way.  It's just as easy and
I feel like I'm in a bit more control.  Here is a sample eruby program to
set a couple cookies:

<%
require 'cgi'

# get an expiration date string for a year from now
ed = CGI.rfc1123_date(Time.now + (60 * 60 * 24 * 365))

r = Apache.request
r.content_type = 'text/html'
r.headers_out.add('Set-Cookie', 'name=frank; path=/; expires=%s' % ed)
r.headers_out.add('Set-Cookie', 'language=eruby; path=/; expires=%s' % ed)
r.send_http_header
%>

<html>
<body>
Here are the headers that came in:
<pre>
<% r.headers_in.each { |h| p h } %>
</pre>
Here are the headers we added and sent out:
<pre>
<% r.headers_out.each { |h| p h } %>
</pre>
</body>
</html>

Note that to use this with mod_ruby or plain cgi you'd just have to
remove the <% and %> markers and then add code to display the html that
eruby is displaying for you.

Let me know if you have any questions.

PS: By the way, since you asked, to delete a cookie you'd just set another
cookie with the same variable and path but with an expiration date in the
past.
