Hi Jawon,
You can do this by using an API call hook, like so:
def urlfetch_timeout_hook(service, call, request, response):
if call != 'Fetch':
return
# Make the default deadline 10 seconds instead of 5.
if not request.has_deadline():
request.set_deadline(10.0)
apiproxy_stub_map.apiproxy.GetPreCallHooks().Append(
'urlfetch_timeout_hook', urlfetch_timeout_hook, 'urlfetch')
