fiddler doesn't capture python http request?

Question

I've tried to use fiddle2 to debug one of my python program which makes http request and gets response. However I didn't see any traffic on fiddler no matter I ran python in command prompt or python GUI. Fiddle filter is not set, i.e., set to show all processes, I did see my browsers' traffic there.

Is there any settings I need to set?

Thanks.

This is the same as [Fiddler does not capture my script's requests](http://stackoverflow.com/questions/7681305/fiddler-does-not-capture-my-scripts-requests). If you want to use Fiddler, you can start with his proxy code, though he is having a problem actually seeing the request. — Matthew Flaschen, Oct 08 '11 at 04:23

Python does not use proxy by default, so fiddler cannot intercept its network traffic. You may need to change the Python program a little. Here is another thread on how to see proxy for Python programs Proxy with urllib2.

It will only work if you set Python to use Fiddler as a proxy. It may be easier to use Wireshark, which will let you monitor all HTTP traffic, without the need for proxies.

If you want to view https content, then fiddler is easier as wireshark can be hard to setup for that. – user352472 Oct 24 '13 at 17:17
