def request_config(original=False):
    """
    Returns the Routes RequestConfig object.

    To get the Routes RequestConfig:

    >>> from routes import *
    >>> config = request_config()

    The following attributes must be set on the config object every request:

    mapper
        mapper should be a Mapper instance thats ready for use
    host
        host is the hostname of the webapp
    protocol
        protocol is the protocol of the current request
    mapper_dict
        mapper_dict should be the dict returned by mapper.match()
    redirect
        redirect should be a function that issues a redirect,
        and takes a url as the sole argument
    prefix (optional)
        Set if the application is moved under a URL prefix. Prefix
        will be stripped before matching, and prepended on generation
    environ (optional)
        Set to the WSGI environ for automatic prefix support if the
        webapp is underneath a 'SCRIPT_NAME'

        Setting the environ will use information in environ to try and
        populate the host/protocol/mapper_dict options if you've already
        set a mapper.

    **Using your own requst local**

    If you have your own request local object that you'd like to use instead
    of the default thread local provided by Routes, you can configure Routes
    to use it::

        from routes import request_config()
        config = request_config()
        if hasattr(config, 'using_request_local'):
            config.request_local = YourLocalCallable
            config = request_config()

    Once you have configured request_config, its advisable you retrieve it
    again to get the object you wanted. The variable you assign to
    request_local is assumed to be a callable that will get the local config
    object you wish.

    This example tests for the presence of the 'using_request_local' attribute
    which will be present if you haven't assigned it yet. This way you can
    avoid repeat assignments of the request specific callable.

    Should you want the original object, perhaps to change the callable its
    using or stop this behavior, call request_config(original=True).
