        Build an absolute URI from the location and the variables available in
        this request. If no ``location`` is specified, build the absolute URI
        using request.get_full_path(). If the location is absolute, convert it
        to an RFC 3987 compliant URI and return it. If location is relative or
        is scheme-relative (i.e., ``//example.com/``), urljoin() it to a base
        URL constructed from the request variables.

    A specialized MultiValueDict which represents a query string.

    A QueryDict can be used to represent GET or POST data. It subclasses
    MultiValueDict since keys in such data can be repeated, for instance
    in the data from a form with a <select multiple> field.

    By default QueryDicts are immutable, though the copy() method
    will always return a mutable copy.

    Both keys and values set on this class are converted from the given encoding
    (DEFAULT_CHARSET by default) to str.

    Validate the given host for this site.

    Check that the host looks valid and matches a host or host pattern in the
    given list of ``allowed_hosts``. Any pattern beginning with a period
    matches a domain and all its subdomains (e.g. ``.example.com`` matches
    ``example.com`` and any subdomain), ``*`` matches anything, and anything
    else must match exactly.

    Note: This function assumes that the given host is lowercased and has
    already had the port, if any, stripped off.

    Return ``True`` for a valid host, ``False`` otherwise.
