In CherryPy 2.1.1, there are two data structures from which
you can
obtain header values. But you should normally only use one
of them:
cherrypy.request.headerMap. This is a dictionary, and you
can get the
Referer header via:
ref = cherrypy.request.headerMap.get('Referer')
if ref:
do_stuff_with_ref(ref)
The other, cherrypy.request.headers, is only there for
people who think
the order in which headers were supplied by the client is
important. It
should be an iterable of (key, value) 2-tuples. But you
shouldn't use
it.
