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!
