I work on CentOS 6.6 and Python is 2.6.6. Pushgateway runs on localhost:9091.

When I push metrics with a URL starts with neither "http://" or "https://", just like push_to_gateway('localhost:9091', job='demo', registry=registry), error occurs as follow:

# python push_demo.py 
Traceback (most recent call last):
  File "push_demo.py", line 19, in <module>
    push_to_gateway('localhost:9091', job='dev', registry=registry)
  File "/usr/lib/python2.6/site-packages/prometheus_client-0.0.21-py2.6.egg/prometheus_client/exposition.py", line 198, in push_to_gateway
    _use_gateway('PUT', gateway, job, registry, grouping_key, timeout, handler)
  File "/usr/lib/python2.6/site-packages/prometheus_client-0.0.21-py2.6.egg/prometheus_client/exposition.py", line 265, in _use_gateway
    headers=headers, data=data)()
  File "/usr/lib/python2.6/site-packages/prometheus_client-0.0.21-py2.6.egg/prometheus_client/exposition.py", line 133, in handle
    resp = build_opener(HTTPHandler).open(request, timeout=timeout)
  File "/usr/lib64/python2.6/urllib2.py", line 391, in open
    response = self._open(req, data)
  File "/usr/lib64/python2.6/urllib2.py", line 414, in _open
    'unknown_open', req)
  File "/usr/lib64/python2.6/urllib2.py", line 369, in _call_chain
    result = func(*args)
  File "/usr/lib64/python2.6/urllib2.py", line 1223, in unknown_open
    raise URLError('unknown url type: %s' % type)
urllib2.URLError: <urlopen error unknown url type: localhost>

I think it's a bug of urlparse in Python26.
