There are three solutions that I know about: 1) Make your own little HTTP library and set timeouts for each of your sockets. 2) The same as the above, except use asynchronous sockets and the the select module. 3) If you're on a Unix style system, use the signal module (the example is helpful http://docs.python.org/library/signal.html#example) Here's some code: import urllib2 import signal class TimeoutException(Exception): """SIGALARM was sent to the process""" pass def raise_timeout(signum, frame): raise TimeoutException("Timeout!") signal.signal(signal.SIGALRM, raise_timeout) try: signal.alarm(5) # raise alarm in 5 seconds data = urllib2.urlopen("http://www.google.com";).readlines() except TimeoutException, ex: data = None finally: signal.alarm(0) # disable alarm HTH, Ben -- http://mail.python.org/mailman/listinfo/python-list
