Quoting from: http://wp.netscape.com/newsref/std/cookie_spec.html

 Syntax of the Cookie HTTP Request Header
 When requesting a URL from an HTTP server, the browser will match the
 URL  against all cookies and if any of them match, a line containing
 the  name/value pairs of all matching cookies will be included in the
 HTTP request. Here is the format of that line: 

  Cookie: NAME1=OPAQUE_STRING1; NAME2=OPAQUE_STRING2 ...

Considering the output of CGI::Cookie to be almost, but not quite what 
you are looking for, I would suggest keeping your cookies in a hash of 
 string => string
instead. Given such a hash: 
 a = { 'foo' => "This is a test ;", 'bar' => 'Cookie value' }
you could then format everything to the left of 'Cookie: ' by doing
 a.collect { |k, v| "#{k}=#{ CGI.escape(v) };" }.join(' ')$
resulting in 
 "foo=This+is+a+test+%3B; bar=Cookie+value;"

The encoding of the cookie value is not covered by the above link; it is 
only to be considered as a rough introduction. There is a rfc (whose 
number I don't have in my head) that describes what CGI.escape does. 

I hope that gets you on track.
