I'm not quite sure what you mean by "cookie shell". Can you explain?

In general, there are two parts to using cookies:
  1) creating the cookie
  2) retrieving the cookie in later requests

Regardless of which programming language you use, cookies are 
transferred the same way: as part of the HTTP protocol. I would 
recommend the Mozilla developer documentation as a good reference:
https://developer.mozilla.org/en-US/docs/Web/HTTP/Cookies

In a Haserl script, you create a cookie by including "Set-Cookie" in the 
HTTP headers. An example would be:

	#!/usr/bin/haserl
	Content-type: text/html
	Set-Cookie: foo=bar

	<html><body>
	<h1>heading</h1>
	</body></html>

Later on, in a subsequent request, you can obtain the value of the
cookie using the variable $COOKIE_foo.

	#!/usr/bin/haserl
	Content-type: text/html

	<html><body>
	<p>Cookie value is <% echo $COOKIE_foo %>.</p>
	</body></html>

Note that in both cases, the HTTP headers should really be using CR+LF 
line termination. See the section "RFC-2616 conformance" of the haserl 
manual at http://haserl.sourceforge.net/manpage.html for details.
