Hello Mark,

Thank you very much for your answer. I guess the "cleanest" way would be to override the PUBLIC_EXTERNAL_ARCHIVER (we don't want to index our private for now). I'll give it a try as soon as possible.
Do you think my script will interest some people ? if so, where should I post it ?

Thanks again

Best regards,
