that traffic go in and out of my server machine? The python docs say
that urllib2 requires the socket library to work, so I assume it's a
socket of some sort, but I don't really understand how that socket
is addressed, from the point of view of the third-party server that
is receiving my urllib2 request, and returning the response.
Virtually all network comms is over sockets. Your web browser
uses sockets every time it connects to a web server. Your web
server is using sockets to receive those requests.
The urllib implementation has to use the Python socket
module so there is a dependency but thats just what you'd expect.
It has to talk to a socket somehow and if it didn't use the socket
library directly it would either use a higher level library that in
turn used socket, or else it would have to implement sockets
itself at the C level.
it appear to be coming from? If my web server (lighttpd in this
case) is set to listen on a particular port, is there any way that
it can 'see' that traffic and interact with it, or is it purely
between the python library and the outside world?
Your web server likely listens on port 80.
The urllib will send to port 80 by default.
