    It also replaces the `rfile` and `wfile` attributes with StringIO
    instances so that we garantee that it won't make any I/O, neighter
    for writing nor reading.

    It has some convenience attributes:

    `headers` -> a mimetype object that can be cast into a dictionary,
    contains all the request headers

    `method` -> the HTTP method used in this request

    `querystring` -> a dictionary containing lists with the
    attributes. Please notice that if you need a single value from a
    query string you will need to get it manually like:

    ```python
    >>> request.querystring
    {'name': ['Gabriel Falcao']}
    >>> print request.querystring['name'][0]
    ```

    `parsed_body` -> a dictionary containing parsed request body or
    None if HTTPrettyRequest doesn't know how to parse it.  It
