Description: Asynchronous Python HTTP Requests for Humans
        ============================================

        Small add-on for the python requests_ http library. Makes use of python 3.2's
        `concurrent.futures`_ or the backport_ for prior versions of python.
        
        The additional API and changes are minimal and strives to avoid surprises.
        
        The following synchronous code:
        
        .. code-block:: python
        
            from requests import Session
        
            session = Session()
            # first requests starts and blocks until finished
            response_one = session.get('http://httpbin.org/get')
            # second request starts once first is finished
            response_two = session.get('http://httpbin.org/get?foo=bar')
            # both requests are complete
            print('response one status: {0}'.format(response_one.status_code))
            print(response_one.content)
            print('response two status: {0}'.format(response_two.status_code))
            print(response_two.content)
        
        Can be translated to make use of futures, and thus be asynchronous by creating
        a FuturesSession and catching the returned Future in place of Response. The
        Response can be retrieved by calling the result method on the Future:
        
        .. code-block:: python
        
            from requests_futures.sessions import FuturesSession
        
            session = FuturesSession()
            # first request is started in background
            future_one = session.get('http://httpbin.org/get')
            # second requests is started immediately 
            future_two = session.get('http://httpbin.org/get?foo=bar')
            # wait for the first request to complete, if it hasn't already
            response_one = future_one.result()
            print('response one status: {0}'.format(response_one.status_code))
            print(response_one.content)
            # wait for the second request to complete, if it hasn't already
            response_two = future_two.result()
            print('response two status: {0}'.format(response_two.status_code))
            print(response_two.content)
        
        By default a ThreadPoolExecutor is created with 2 workers. If you would like to
        adjust that value or share a executor across multiple sessions you can provide
        one to the FuturesSession constructor.
        
        .. code-block:: python
        
            from concurrent.futures import ThreadPoolExecutor
            from requests_futures.sessions import FuturesSession
        
            session = FuturesSession(executor=ThreadPoolExecutor(max_workers=10))
            # ...
        
        As a shortcut in case of just increasing workers number you can pass
        `max_workers` straight to the `FuturesSession` constructor:
        
        .. code-block:: python
        
            from requests_futures.sessions import FuturesSession
            session = FuturesSession(max_workers=10)
        
        FutureSession will use an existing session object if supplied:
        
        .. code-block:: python
        
            from requests import session
            from requests_futures.sessions import FuturesSession
            my_session = session()
            future_session = FuturesSession(session=my_session)
        
        That's it. The api of requests.Session is preserved without any modifications
        beyond returning a Future rather than Response. As with all futures exceptions
        are shifted (thrown) to the future.result() call so try/except blocks should be
        moved there.
        
        Working in the Background
        =========================
        
        There is one additional parameter to the various request functions,
        background_callback, which allows you to work with the Response objects in the
        background thread. This can be useful for shifting work out of the foreground,
        for a simple example take json parsing.
        
        .. code-block:: python
        
            from pprint import pprint
            from requests_futures.sessions import FuturesSession
        
            session = FuturesSession()
        
            def bg_cb(sess, resp):
                # parse the json storing the result on the response object
                resp.data = resp.json()
        
            future = session.get('http://httpbin.org/get', background_callback=bg_cb)
            # do some other stuff, send some more requests while this one works
            response = future.result()
            print('response status {0}'.format(response.status_code))
            # data will have been attached to the response object in the background
            pprint(response.data)
