Yeah, that was very helpful. The problem is solved.

For the records, here is my little script to change a config setting and
reparse all konquerors afterwards:

=== cut ===
#!/bin/sh

case $1 in
        offline) ACTION="offline" && VALUE="CacheOnly" ;;
        *)       ACTION="online" && VALUE="Refresh" ;;
esac

echo "Going $ACTION..."

# Changing configuration
sed -i s/^cache=.*/cache=$VALUE/ ~/.kde/share/config/kio_httprc

# Fetch a list of all running kde applications
APPS=$(dcop)

# Define which apps you would like to apply the setting to
# (other applications will not notice the change before the next restart)
APPLYTO="konqueror kcontrol"

for i in ${APPS}; do
 echo "$APPLYTO" | grep -vq "$(echo $i | sed -e 's/-[0-9]*$//')" && continue
 # echo "Using $i ..."
 dcop $i KIO::Scheduler reparseSlaveConfiguration http # 2>/dev/null
done

=== cut ===

Regards, michael
