Comment 5 for bug 811044

I think this may be a bug in Jenkins not in your Python implementation (or perhaps a feature - I've not yet found any documentation as to whether POST requests are supposed to work?)

If I try submitting a job using wget:

wget --auth-no-challenge --http-user=[user] --http-password=[password] --no-check-certificate https://tom-jdvm.redembedded.com/jenkins/job/poetry_writer/buildWithParameters?[params]

it works, but if I add

--post-data=""

which has the effect of making the request a POST not a GET, I get 403 forbidden.

I'll investigate this further and maybe raise a Jenkins bug.

Sorry for bugging you...
