Retrieving and passing a cookie

Hi everyone,

I am trying to sign into a page at eBay to start auctions.  Their lister 
requires a cookie, however, there are 4 review pages before the auction can 
actually be submitted.  At www.ebay.com then click on SELL, you can see the 
source code.  I need:

how to retrieve the cookie, since it is in the header
how to pass that back on and appear to be continously logged on
(we are using a brouser-based lister)
(we are using kurl)


Thanks for any help everyone!
