Requests timeout not working as expected

[garg10may]

Please refer to our Stack Overflow tag for guidance.
requests.get('http://www.google.co.in', timeout=0.001)

Using above on one server works fine but on another server where probably outside access is not allowed requests doesn't timeout the request and only fails after few seconds with below error.

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

What am I doing wrong or how can I make it timeout?

[sethmlarson]

This is because name resolution doesn't take the timeout into account. This is a lower-level issue than requests, see urllib3/urllib3#1334.

ok, thanks. I will try using python signal.
