Timeout when using urllib2.urlopen with Django in GAE

When I run this code

url = ('http://maps.google.com/maps/nav?'+
       'q=from%3A'+from_address+
       '+to%3A'+to_address+
       '&output=json&oe=utf8&key='+api_key)
request = urllib2.Request(url)
response = urllib2.urlopen(request)

In a simple view in Django running in google app engine via the Google App Engine Helper for Django I get an ApplicationError: 2 timed out exception, but when I run the same code in python's or Django's shell it works just fine.

Any ideas what's going on? Thanks!

you can avoid the 10 second deadline by using googles asynchronous fetch service, which accepts deadlines of up to 60 seconds. https://developers.google.com/appengine/docs/python/urlfetch/asynchronousrequests

This is because App Engine has a default timeout of 5 seconds for these calls. If you use UrlFetch [1] you can use the deadline parameter to set the timeout up to a maximum of 10 seconds. If the page you are trying to get takes longer than that, you are out of luck.
