fix: replace bad reverted code change; allow js rate headers Last commit included an incorrect undo. I was going to move the Allow header/output format parsing earlier in the dispatch method. But I reverted it incorrectly and removed it instead. It has been added back in the former location. Header that allows javascript access to the rest rate limit header has been moved. The rate limit headers can be accessed by client side javascript regardless of the rate limit being exceeded.

try:
    # Python 3+.
    from xmlrpc import client, server
    server.SimpleXMLRPCDispatcher
except (ImportError, AttributeError):
    # Python 2.
    import xmlrpclib as client  # noqa: F401
    import SimpleXMLRPCServer as server
