Are you asking if lime wire used Gnutella Web Cache for bootstrapping? I’m not sure. GWebCache is one of many possible ways to boot strap, and I have not run lime wire in over a decade. I saw that GTKGnutella moved off of GWebCache sometime ago and uses some sort UDP based tool now. I am fairly certain that Shareaza still uses it because I see those results come up in my Web cache pull from time to time. I have seen a few advertisements from lime wire fork projects as well.
If I recall, proprietary clients usually shipped with their own bootstrap server. I think it may have even contributed to the legal cases, but it's been a long time.
Every limewire client was a host cache and came with a bootstrap list of ips of one kind or another. One feature that I'm surprised that Bitcoin didn't use.
