but we can't block big over quota downloads. say user trying to download iso image, at the time of request we *don't* know size of the object requested, if we want to block over quota downloads we *must* know it, but we don't. Maybe this could be solved by sending HEAD request in the self written redirector program and compare "Content-lenght:" field if present with current user quota. i don't know. Also we can't handle situation when user asked for big download and cancelled it during the process. olegs P.S. we are using self coded billing with squid and since there are no squid hackers among us we don't know how to fight this feature.
