URLLIB2 EXCEPTION

[bart]

I use function urllopen to connect to http web page. When resource
doesn't present in location, urllopen returns exception. The web server,
in this occasion, generates a page to communicate the error, but urlopen
doesn't return it.

What can I do to receive error page source code by urlopen?

Thanks ...

italian languagge translate:

Utilizzo la funzione urlopen per connettermi a pagine web. Quando la
risorsa non esiste, urlopen ritorna un'eccezione e non il codice
sorgente della pagina generata dal web server in questi casi.

Come posso fare per recuperare tale pagina?

Grazie...

Sometime, when I use urlopen function, happen this:

Traceback (most recent call last):

return _opener.open(url, data)

File "/usr/local/lib/python2.2/httplib.py", line 231, in _read_status
line = self.fp.readline()
IOError: [Errno 104] Connection reset by peer

I understood that connection can be reseted but I managed this exception
cases: HTTPError and URLError. I don't know another exception that can
be generate in urllib2. Besides IOError exception doesn't present inside
urllib2. What can I do to resolve my problem? Where I can found (web
site, manual and other) a solution?

Thanks to help me...
