And of course that's bolloks:
Python 2.7.5 (default, Aug 29 2013, 15:13:35)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.environ.get('HTTP_REFERER','UnkownRef')
'UnkownRef'
>>>
Python 3.2.5 (default, Aug 29 2013, 15:19:46)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.environ.get('HTTP_REFERER','UnkownRef')
'UnkownRef'
