This is handled in such a way that it is completely transparent to the 
application. The application operates in "requests" which is creating a 
request object and passing it to libwww. A request may be to the same host 
or to multiple hosts - it doesn't matter. The net manager (HTNet.c) handles 
all connections including if the remote server is capable of using 
persistent connections.

Therefore, as an application you can safely issue new requests at any point 
in time. If the number of requests is bigger than the number of open sockets 
then the requests are queued up in the HTNet manager and started when a 
socket is available.
