If cookies are returned, then one is placed into cookie-data, and the other is accessible as tmp/set-cookie } Purpose: { To grab cookies from the server and post form data. } Email: [%grossdog--dartmouth--edu %gchiu--compkarori--co--nz] Notes: { Modification of Andrew Grossman's cookies-client script by Graham Chiu.
