Yes, it's possible.

When making a url request, you would send the cookie by setting the 
httpHeaders property. I can't remember exactly the format for a cookie 
header, but it's be something like this:

   Cookie: name=value

So you would do something like this (very roughly) in your script:

     put <some name> into tCookieName
     put <some data> into tCookieValue
     set the httpHeaders to "Cookie: " & tCookieName & "=" & tCookieValue
     get url myUrl
     set the httpHeaders to empty

To get the cookie that is sent by the server, you would use 
libUrlLastRHHeaders() and parse the data for the "Set-Cookie" header.
