I am using buildbot version 0.8.5 and need to send an HTTP post request from it as a step. After searching for it on internet, I found that the latest version 0.8.8 has a step called HTTPStep for doing so. Is there any similar step in the older version?
I know it can be done using batch file or python program using urllib2. but is there any other way to do it?
Just my thoughts..As far as I know it is better to use a python script from a build step. Simple and easy to control. The logic being:

the entire buildbot is inside one http connection/session and sending another http request somewhere might have issues with the connection/session.
from the buildbot httpstep description, you need to install additional python packages which might be not be so convenient to do on multiple slaves/masters.
