I knew one client joined Gnutella should through connect to the other client that have joined Guntella.but I don't know how did the new one find out address of the other one and connect to it? someone said there is tool named Gnutella web cache, it was used by Gnutella to make an initial connection to their respective networks. so who can explain the process about how it works?

This is my first propose one question,so Pls do me a favor.Thank you very mach
