  • Revision ID: v.ladeuil+lp@free.fr-20070506065957-4jdlek9i5at2qb36
Fix bug #112719 by using the right range header.

* HTTPTestUtil.py:
(SingleOnlyRangeRequestHandler): Noisily refuses mutliple range
requests.

* test_http.py:
(TestSingleOnlyRangeRequestServer): Test the retry mechanism when
a server refuses to handle a mutiple range request without
silently replying with a single range or full file response.

* _pycurl.py:
(PyCurlTransport._get_ranged): The header have been built taken
into account the range hint, don't rebuilt it *ignoring* that
hint.
