reliable than reading from any of Django's own properties, as those don't

Efficient data structure for manipulating HTTP headers.
A :class:`list` of ``(name, values)`` is inefficient for lookups.
A :class:`dict` doesn't suffice because header names are case-insensitive
and multiple occurrences of headers with the same name are possible.
:class:`Headers` stores HTTP headers in a hybrid data structure to provide
efficient insertions and lookups while preserving the original data.
In order to account for multiple values with minimal hassle,
:class:`Headers` follows this logic:
- When getting a header with ``headers[name]``:
- if there's no value, :exc:`KeyError` is raised;
- if there's exactly one value, it's returned;
- if there's more than one value, :exc:`MultipleValuesError` is raised.
- When setting a header with ``headers[name] = value``, the value is
appended to the list of values for that header.
- When deleting a header with ``del headers[name]``, all values for that
header are removed (this is slow).
Other methods for manipulating headers are consistent with this logic.
As long as no header occurs multiple times, :class:`Headers` behaves like
:class:`dict`, except keys are lower-cased to provide case-insensitivity.
Two methods support manipulating multiple values explicitly:
- :meth:`get_all` returns a list of all values for a header;
- :meth:`raw_items` returns an iterator of ``(name, values)`` pairs.

a :data:`~websockets.datastructures.HeadersLike` or a callable
taking the request path and headers in arguments and returning
a :data:`~websockets.datastructures.HeadersLike`.
process_request (Optional[Callable[[str, Headers], \
Awaitable[Optional[Tuple[http.HTTPStatus, HeadersLike, bytes]]]]]):
intercept HTTP request before the opening handshake;
see :meth:`~WebSocketServerProtocol.process_request` for details.

See :class:`~websockets.legacy.protocol.WebSocketCommonProtocol` for the
documentation of ``ping_interval``, ``ping_timeout``, ``close_timeout``,
``max_size``, ``max_queue``, ``read_limit``, and ``write_limit``.
Any other keyword arguments are passed the event loop's
:meth:`~asyncio.loop.create_server` method.
For example:
* You can set ``ssl`` to a :class:`~ssl.SSLContext` to enable TLS.
* You can set ``sock`` to a :obj:`~socket.socket` that you created
outside of websockets.
Returns:

class WebSocketCommonProtocol(asyncio.Protocol):
"""
WebSocket connection.
:class:`WebSocketCommonProtocol` provides APIs shared between WebSocket
servers and clients. You shouldn't use it directly. Instead, use
:class:`~websockets.client.WebSocketClientProtocol` or
:class:`~websockets.server.WebSocketServerProtocol`.
This documentation focuses on low-level details that aren't covered in the
documentation of :class:`~websockets.client.WebSocketClientProtocol` and
:class:`~websockets.server.WebSocketServerProtocol` for the sake of
simplicity.
Once the connection is open, a Ping_ frame is sent every ``ping_interval``
seconds. This serves as a keepalive. It helps keeping the connection
open, especially in the presence of proxies with short timeouts on
inactive connections. Set ``ping_interval`` to :obj:`None` to disable
this behavior.
.. _Ping: https://www.rfc-editor.org/rfc/rfc6455.html#section-5.5.2
If the corresponding Pong_ frame isn't received within ``ping_timeout``
seconds, the connection is considered unusable and is closed with code
1011. This ensures that the remote endpoint remains responsive. Set
``ping_timeout`` to :obj:`None` to disable this behavior.
.. _Pong: https://www.rfc-editor.org/rfc/rfc6455.html#section-5.5.3
The ``close_timeout`` parameter defines a maximum wait time for completing
the closing handshake and terminating the TCP connection. For legacy
reasons, :meth:`close` completes in at most ``5 * close_timeout`` seconds
for clients and ``4 * close_timeout`` for servers.
See the discussion of :doc:`timeouts <../topics/timeouts>` for details.
``close_timeout`` needs to be a parameter of the protocol because
websockets usually calls :meth:`close` implicitly upon exit:
* on the client side, when :func:`~websockets.client.connect` is used as a
context manager;
* on the server side, when the connection handler terminates;
To apply a timeout to any other API, wrap it in :func:`~asyncio.wait_for`.
The ``max_size`` parameter enforces the maximum size for incoming messages
in bytes. The default value is 1 MiB. If a larger message is received,
:meth:`recv` will raise :exc:`~websockets.exceptions.ConnectionClosedError`
and the connection will be closed with code 1009.
The ``max_queue`` parameter sets the maximum length of the queue that
holds incoming messages. The default value is ``32``. Messages are added
to an in-memory queue when they're received; then :meth:`recv` pops from
that queue. In order to prevent excessive memory consumption when
messages are received faster than they can be processed, the queue must
be bounded. If the queue fills up, the protocol stops processing incoming
data until :meth:`recv` is called. In this situation, various receive
buffers (at least in :mod:`asyncio` and in the OS) will fill up, then the
TCP receive window will shrink, slowing down transmission to avoid packet
loss.
Since Python can use up to 4 bytes of memory to represent a single
character, each connection may use up to ``4 * max_size * max_queue``
bytes of memory to store incoming messages. By default, this is 128 MiB.
You may want to lower the limits, depending on your application's
requirements.
The ``read_limit`` argument sets the high-water limit of the buffer for
incoming bytes. The low-water limit is half the high-water limit. The
default value is 64 KiB, half of asyncio's default (based on the current
implementation of :class:`~asyncio.StreamReader`).
The ``write_limit`` argument sets the high-water limit of the buffer for
outgoing bytes. The low-water limit is a quarter of the high-water limit.
The default value is 64 KiB, equal to asyncio's default (based on the
current implementation of ``FlowControlMixin``).
See the discussion of :doc:`memory usage <../topics/memory>` for details.
Args:
logger: logger for this connection;
defaults to ``logging.getLogger("websockets.protocol")``;
see the :doc:`logging guide <../topics/logging>` for details.
ping_interval: delay between keepalive pings in seconds;
:obj:`None` to disable keepalive pings.
ping_timeout: timeout for keepalive pings in seconds;
:obj:`None` to disable timeouts.
close_timeout: timeout for closing the connection in seconds;
for legacy reasons, the actual timeout is 4 or 5 times larger.
max_size: maximum size of incoming messages in bytes;
:obj:`None` to disable the limit.
max_queue: maximum number of incoming messages in receive buffer;
:obj:`None` to disable the limit.
read_limit: high-water mark of read buffer in bytes.
write_limit: high-water mark of write buffer in bytes.

strings, bytestrings, or bytes-like objects to enable fragmentation_.
Each item is treated as a message fragment and sent in its own frame.
All items must be of the same type, or else :meth:`send` will raise a
:exc:`TypeError` and the connection will be closed.
.. _fragmentation: https://www.rfc-editor.org/rfc/rfc6455.html#section-5.4
:meth:`send` rejects dict-like objects because this is often an error.
(If you want to send the keys of a dict-like object as fragments, call
its :meth:`~dict.keys` method and pass the result to :meth:`send`.)
Canceling :meth:`send` is discouraged. Instead, you should close the
connection with :meth:`close`. Indeed, there are only two situations
where :meth:`send` may yield control to the event loop and then get
canceled; in both cases, :meth:`close` has the same effect and is
more clear:
1. The write buffer is full. If you don't want to wait until enough
data is sent, your only alternative is to close the connection.
:meth:`close` will likely time out then abort the TCP connection.
2. ``message`` is an asynchronous iterator that yields control.
Stopping in the middle of a fragmented message will cause a
protocol error and the connection will be closed.
When the connection is closed, :meth:`send` raises
:exc:`~websockets.exceptions.ConnectionClosed`. Specifically, it
raises :exc:`~websockets.exceptions.ConnectionClosedOK` after a normal
connection closure and
:exc:`~websockets.exceptions.ConnectionClosedError` after a protocol
error or a network failure.
Args:
message (Union[Data, Iterable[Data], AsyncIterable[Data]): message
to send.
Raises:
ConnectionClosed: when the connection is closed.
TypeError: if ``message`` doesn't have a supported type.

.. _Text: https://www.rfc-editor.org/rfc/rfc6455.html#section-5.6
.. _Binary: https://www.rfc-editor.org/rfc/rfc6455.html#section-5.6
:func:`broadcast` pushes the message synchronously to all connections even
if their write buffers are overflowing. There's no backpressure.
:func:`broadcast` skips silently connections that aren't open in order to
avoid errors on connections where the closing handshake is in progress.
If you broadcast messages faster than a connection can handle them,
messages will pile up in its write buffer until the connection times out.
Keep low values for ``ping_interval`` and ``ping_timeout`` to prevent
excessive memory usage by slow connections when you use :func:`broadcast`.
Unlike :meth:`~websockets.server.WebSocketServerProtocol.send`,
:func:`broadcast` doesn't support sending fragmented messages. Indeed,
fragmentation is useful for sending large messages without buffering
them in memory, while :func:`broadcast` buffers one copy per connection
as fast as possible.
Args:
websockets (Iterable[WebSocketCommonProtocol]): WebSocket connections
