multiple cookies in a single response

Dick Heijink
Hello list,

I am new to this list, so please excuse me if this is not the appropriate place for my question.
We're developing a web application using the Hyper Server. We ran into some problems when we tried to set multiple cookies in a single response. Although Hyper 'correctly' implements the RFC that states that multiple cookies should be comma separated into a single Set-Cookie field, most browsers have different ideas about this.
See http://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_cookies for more information on browsers and their cookie behavior.
Contrary to what the RFC states, all browsers accept multiple Set-Cookie headers in a response. I've implemented this behavior in Hyper by changing the valueAsStringOn instance method in the HyHTTPSetCookie class.

valuesAsStringOn: aStream
    aStream nextPutAll: (self cookies at: 1).
    2
        to: self cookies size
        do:
            [:cookieIndex |
            aStream
                crlf;
                nextPutAll: self name;
                nextPutAll: ': ';
                nextPutAll: (self cookies at: cookieIndex)].
    ^self

Has anybody else experienced problems using multiple cookies in a single response?

Dick,

Firstly, this list is absolutely the right place for such questions.

I confess that I don't use cookies at all, so I can't say that I have
run into the problem you see.

Thank you very much for bringing this up.   May I include you code in
future versions of Hyper under the LGPL?   I will credit you, of
course.   I'll have a look at the link you gave and run some tests.

Many thanks,
    Bruce

Thank you for quick response, Bruce.

Please feel free to adapt the code to suit your needs/coding practices.

Yes we (Seaside) did and reported it here. We were told that this is a
bug in browsers (which we agree on) so there's no need to fix it in
Swazoo (which we disagree on).

Seaside hacks around it with a custom cookie header class.

Cheers
Philippe

Well, I'll be fixing this in Hyper.  :-)
