CouchDB cookie from outside CouchDB

[CGS]

Hi all,

I have few web applications which each requires login and I am trying to 
unify their login procedures. One of the applications is CouchDB 
(obviously) and, as far as I noticed, this application uses cookie 
system to save the login session. Does anyone know what JavaScript files 
I should load into the common login page and what to do to create that 
cookie?

I know there is an option to transfer the login session via address bar, 
but I do not fancy that option too much. That's why I try to create the 
cookie and I am trying to "hack" futon, but I would appreciate any help 
if any of you managed this before. Thank you.

Cheers,
CGS
