# this is an example script of how you could manage your cookies..
# we use the cookies.txt format (See http://kb.mozillazine.org/Cookies.txt)
# This is one textfile with entries like this:
# kb.mozillazine.org FALSE / FALSE 1146030396 wikiUserID 16993
# domain alow-read-other-subdomains path http-required expiration name value
# you probably want your cookies config file in your $XDG_CONFIG_HOME ( eg $HOME/.config/uzbl/cookies)
# Note. in uzbl there is no strict definition on what a session is. it's YOUR job to clear cookies marked as end_session if you want to keep cookies only valid during a "session"
# MAYBE TODO: allow user to edit cookie before saving. this cannot be done with zenity :(
# TODO: different cookie paths per config (eg per group of uzbl instances)
# TODO: correct implementation.
# see http://curl.haxx.se/rfc/cookie_spec.html
# http://en.wikipedia.org/wiki/HTTP_cookie
# TODO : check expires= before sending.
# write sample script that cleans up cookies dir based on expires attribute.
# TODO: check uri against domain attribute. and path also.
# implement secure attribute.
# support blocking or not for 3rd parties
# http://kb.mozillazine.org/Cookies.txt
# don't always append cookies, sometimes we need to overwrite
