No.
The server does not reset the connection.
It is the router/firewall.

Ok, I have now:
 try:
 req = urllib.Request(szurl)
 req.add_header('User-Agent',useragent)
 u = urllib.urlopen(req)
 except urllib.URLError as e:
 die('cannot get %s - %s' % (szurl,e.reason))
 except urllib.HTTPError as e:
 die('cannot get %s - server reply: %d %s' % (szurl,e.code,e.reason))
 except (IOError,httplib.BadStatusLine,httplib.HTTPException):
 die('cannot get %s - connection reset by router or firewall' % szurl)
 except socket.error as msg:
 die('cannot get %s - %s' % (szurl,msg))
