    request or parts of it.  Here an example:

>>> from werkzeug import create_environ
    >>> env = create_environ("/?param=foo", "http://localhost/script")
    >>> get_current_url(env)
    'http://localhost/script/?param=foo'
    >>> get_current_url(env, root_only=True)
    'http://localhost/script/'
    >>> get_current_url(env, host_only=True)
    'http://localhost/'
    >>> get_current_url(env, strip_querystring=True)
    'http://localhost/script/'

:param environ: the WSGI environment to get the current URL from.
    :param root_only: set `True` if you only want the root URL.
    :param strip_querystring: set to `True` if you don't want the querystring.
    :param host_only: set to `True` if the host URL should be returned.

    Naively yank the first IP address in an X-Forwarded-For header
    and assume this is correct.

Note: Don't use this in security sensitive situations since this
    value may be forged from a client.
