Cool, thank you a lot, it is exactly what I have been looking for.
It is working fine with Konqueror, Epiphany and Mozialla, but somehow not with my current Firefox Version (Mozilla/5.0 (X11; U; Linux i686; de-DE; rv:1.7.12) Gecko/20050922 Firefox/1.0.7 (Debian package 1.0.7-1).
I will try tomorrow with the IE and Firefox at work and give Feedback how it is working with those browsers.
