You might find you need to examine the HTTP response headers and access
another page. I think that httplib does that for you, but you will have to
code it yourself with asyncore. Here's a trace from a proxy trying to access
that page on my browser's behalf. Did I get anything wrong? I cam certainly
access the page in IE. In this case the server might not have liked the
apparently-spoofed "Host:" header which the proxy just dumbly echoes out.
By the way, the proxy is another Rushing-inspired tool!
