Answer 1

The client authenticates with the socks server only once per connection. The client connects to the socks server and passes it the requested destination address/host, port, and socks authentication credentials, if any. If the socks server accepts the request then it connects to the destination server and notifies the client of the result. If successful, any subsequent data the client sends to the socks server is sent as-is to the destination server, and vice versa any data the destination server sends is passed as-is to the client, back and forth for the lifetime of the connection. If the client uses http keep-alives then it can request multiple web resources using a single connection. Otherwise, it has to reconnect and reauthorize for every new connection it makes.
