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))
