can I add a new name-pair to an existing cookie?

[Kevin Blount]

I have an issue with trying to add a new name-pair to an existing
cookie. Here's what I want to do:

page1 -
adds "loggedin=true" to cookie "Communities"
adds "member_id=100" to cookie "Communities"

page2 -
adds "banner=1" to cookie "Communities"

page 3 -
reads cookie "Communities"

first I would run page 1, then page 2 and finally page 3

in original ASP if I did this page would show something like:
cookie name: "Communities"
cookie value: "loggedin=true&member_id&100&banner=1"

but in my ASP.NET (C#) scripts, page 3 shows:
cookie name: "Communities"
cookie value: "banner=1"

it seems page 2 overwrites the cookie. Is there any way to add the
name-pair from page 2 without overwriting those from page 1?

If necessary I will stop using collections and just make multiple
cookies with a common prefix (such as commLoggedIn, commBanner, etc),
but I'd really like to keep collections, and in my current ASP code
(which is being updated to .NET) I have multiple collections.

I guess I could try and write a function that is passed a new or
existing name-value pair; reads the current value of the collection and
adds each one back individually either updating one or adding a new
one, but that seems too much effort.

any help appreciated

you'd need to first extract the value of the cookie and append to it then
store it back.

Thanks for the reply.

I figured, after hours of research, that would be the case. Seems a
chame that in this case ASP.NET is a step back from original ASP, but
maybe I'm missing something as to why is had to be done this way.

cheers
