Re: Squid source code

The list is populated during peer selection / ICP pinging. More
specifically in peerSelectFoo().

Squids request processing looks something like

1. Read and decode the request headers from the client
2. Access control
3. Redirection
4. Peer selection, building the linked list of peers to try (where
DIRECT is one kind of peer). Each call to peerAddFwdServer adds another
server to the list.
5. forward.c, forwards the request to the first selected peer
6. protocol specific code.
7. If failure, then forward.c tries the next peer in the list.
