Hi Aleksey and Tej, Thanks for the input. I didn't look at the latest NSS code yet, so that's the first thing on my list. As soon as I have something, which I think is a bit usefull and workable, I'll send the code around, to be added to CVS (if it makes any sense to you guys ;) But probably you'll hear from me sooner with (other) questions. Regards, Wouter
