Thanks to you both. I'll read up on sockets, but it seems unlikely
that it works the way I thought it might...

I'd like to be able to see the response coming back from the third-
party
server, and have lighttpd check its headers and either intercept it
or allow
it back into the framework. Say if it's got a text content-type
then let it
in to the framework, and if it's got an image content-type then
ignore it or
throw it away. Rephrasing it this way makes it sound pretty
unlikely. I
guess what I wanted was a better sense of how urllib2 uses a socket
to make
the request, and how the response, on its way back to my server,
finds that
socket. I thought that if the socket file was something that hung
around
between requests, I might be able to configure lighttpd to 'listen
in' on
that socket, and grab the response if it met certain criteria. But
if that
were possible then urllib2 would raise an error, right?
lighttpd will not see the traffic to the third-party server; the tp
server is not making a request of lighttpd; your code is making a
request of it. The response comes back on the same socket that was
opened by the request; if you want to know how they match up you will
have to learn about TCP/IP which is the underlying network protocol.
This might help:

If you want to filter the response according to the headers, you can
do that in your code. The response object returned by urllib2 includes
an info() method that gives access to the response headers.
