How do you access JavaScript cookies from ASP?

I am working on a site that was written in ASP (VBScript) and added a Javascript/CSS based "disclaimer" that i want to show up the first time site is loaded after logging in.

The way the script works is that if there is no cookie named "droppedin" then it sets one and displays the disclaimer as an animated/fly-in window.

I want the logout page (logout.asp) to clear this cookie. I have tried the following:

Response.Buffer = true
Response.CacheControl = "no-cache"
Response.AddHeader "Pragma", "no-cache"
Response.Expires = -1
Server.ScriptTimeout = 60

Session("uid") = ""
Session("pass") = ""
Session("group") = ""
Session("shift") = ""
Session("UserAuth") = ""
Session("UserAdmin") = ""
Response.Cookies("droppedin") = ""
Response.Redirect("login.asp")

This does not clear the cookie. Using TamperData in Firefox, the cookie values show as follows (note 2 droppedin cookies):

Cookie=droppedin=yes; droppedin=; ASPSESSIONIDCCACSRDS=GDNPECNDBANFJKFAAOLOMMDI

How can I access a cookie set by JavaScript and re-set it from ASP/VBScript?

At Logout.asp you could tell the cookie to Expire immediately, using

response.cookies("droppedin").expires=now

this essentially 'destroys' the cookie.

The issue is it's not overriding the initial cookie. It's creating a separate cookie with the same name. The Javascript sets it's own cookie and the ASP code sets another one. I want them to overwrite/share the cookie, or be able to change the variable.

That would expire the "ASP" cookie, but not the JavaScript cookie.

This introduces a possible workaround, by passing the Javascript and ASP calls back and forth through page requests. Not the best solution, but the best so far. If Mahalo didn't give the other response Best Answer already, I'd give it to you as the other response suffers the same issue I've been having
