Amplififying on Stas's reply, there's a big difference between incoming
(request) cookies and outgoing (response) cookies. When you set
(or bake) a cookie, it's _outgoing_, so you're ultimately creating
something that will only appear in the *response* headers. On the
other hand, when these modules parse cookies, they're only looking
at the *request* headers, since that's where the *incoming* cookies
appear.
IOW, you shouldn't try to set/bake cookies as a means of passing
data from one handler to another one *inside the same request*.
Cookies are a means of passing data between two different requests,
and the module APIs reflect that.
