This script is a downloader with support for cookies. Since it uses the switch –content-disposition it saves files with proper names instead of download.php?fa90394892384 and the likes. It relies on notify-send for sending notifications. Based on dl-cookies.sh

Copy this script to @scripts_dir/dl-dbus.sh.

#!/bin/bash
DOWNLOAD_FOLDER=$HOME/incoming
cookies="$XDG_DATA_HOME/uzbl/cookies.txt"
WGET="wget --user-agent=Firefox --content-disposition\
	--no-check-certificate --quiet --load-cookies $cookies"
	notify-send --icon /usr/share/uzbl/examples/data/uzbl.png ::uzbl:: "started download of $8"
    cd $DOWNLOAD_FOLDER
    $WGET $8 && notify-send --icon /usr/share/uzbl/examples/data/uzbl.png "::uzbl:: \"$8 downloaded to $DOWNLOAD_FOLDER\"" 

Just put

@on_event   DOWNLOAD_REQUEST    spawn @scripts_dir/dl-dbus.sh %s

in your config and your done.
