I understand that. In Python using sockets is like using sockets in C.
However, I was looking for a python equivalent of the perl idiom of
opening a socket and getting a file handle ... and then reading this
file handle as any other line oriented file using $socket->readline
I am trying to write a simple Netcraft style script which tries the HEAD
method on a webserver and reads the Server: header from the response. I
would not like to use urllib, because even a call to something like
urllib.info() reads in the complete webpage on an open().
Even if this particular problem could be done elegantly, I would be
interested to know the answer to my original question because the
feature of reading a line at a time from a socket will help me in a lot
of other places in the future.
