Hi,
Is UDP (or RUDP) used in download or upload operation ?? Where could I read a documentation about this ??

Very tanks

UDO is mainly used in search packets - not so much in downloading/uploading

not been used for transfering file at all

LimeWire uses UDP instead of TCP if the latter cannot be used for file transfers. It's not just query hits.
Shareaza however supports very little of the Gnutella protocol.
I doubt it supports *any* feature added to Gnutella after 2002 or so.

Im adding it now to the pre-2.3 version of shareaza....

Shareaza is cool cuz it handles 3 nets instead of 1 or 2, but, in this moment, Shareaza does NOT support so much the Gnutella protocol, that fact should be enforced a little

With the edition of UHC support in the daily builds right now I say thats a BIG plus

It connects just as fast as limewire now
