Etherpad behind reverse proxy

[dpellow]

Does this interface work when etherpad is setup as described here: https://github.com/ether/etherpad-lite/wiki/How-to-put-Etherpad-Lite-behind-a-reverse-Proxy#with-ssl-enabled-requiring-authentication-and-allowing-nice-urls

I have followed the directions there on setting up etherpad behind a reverse proxy with apache, ssl, and requiring authentication. When I try to follow the simple usage example here

$ python -m etherpad_lite -p apikey=secret_from_APIKEY.txt
% createPad padID=test text="Lorem ipsum dolor sit amet."

I get the following error:

Traceback (most recent call last):

  File "/usr/lib/python2.7/httplib.py", line 371, in _read_status
    raise BadStatusLine(line)
httplib.BadStatusLine: ''

Is there something that I need to modify or a different command line parameter that I need to use that will let me do this?
