I agree, however I'm not sure about making REBOL deal with cookies
Anyway, the functionality is almost already there.

You can get the cookie from p/locals/headers/Set-Cookie, except
that PARSE-HEADER has problems with repeated headers and you only
get to see the last one in the object. A quick hack migth be to
read directly header-rules/head-list which has all of them.
You can send cookies back using the /CUSTOM refinement. Here the
problem of using repeated headers is harder to workaround, and you
probably need to poke into the handler code to make it work;
anyway, it's something like:
read/custom http://somesite/ [
header [Cookie: "my-cookie=something"]
I think that some of these problems have been fixed during the
View 1.3 project.
