[Seaside] cookies

[Philippe Marschall]

Hi

I'm currently reviewing our cookie support. One of the things I noted
is that whereas cookies in WAResponse is a Set of WACookie in the
WARequest is a Dictionary mapping String to String. This allows for
easy programming like:

aReqest cookies keysAndValuesDo: [ :key :value |
     ....

but is quite inconsistent. Any opinions on this? How often are cookies
read from the request?

Cheers
Philippe
