is it impossible to download on a bearshare client ?

for example on a NORMAL gnutella client, the url are http://<machine>:<port>/get/<index>/mymp3.mp3


on a BEARSHARE, it is
http://<machine>:<port>/get/<index>/mymp3.mp3?auth=121fd45

the auth permits to Bearshare not to SHARE
with the gnutella community !

BAN BEARSHARE !
