If the handshake request is valid and the handshake successful, :meth:`accept` returns an HTTP response with status code 101. Else, it returns an HTTP response with another status code. This rejects the connection, like :meth:`reject` would. You must send the handshake response with :meth:`send_response`. You may modify the response before sending it, typically by adding HTTP headers. Args: request: WebSocket handshake request received from the client.

Accept or reject each extension proposed in the client request. Negotiate parameters for accepted extensions. Per :rfc:`6455`, negotiation rules are defined by the specification of each extension. To provide this level of flexibility, for each extension proposed by the client, we check for a match with each extension available in the server configuration. If no match is found, the extension is ignored. If several variants of the same extension are proposed by the client, it may be accepted several times, which won't make sense in general. Extensions must implement their own requirements. For this purpose, the list of previously accepted extensions is provided. This process doesn't allow the server to reorder extensions. It can only select a subset of the extensions proposed by the client. Other requirements, for example related to mandatory extensions or the order of extensions, may be implemented by overriding this method. Args: headers: WebSocket handshake request headers. Returns: ``Sec-WebSocket-Extensions`` HTTP response header and list of accepted extensions. Raises: InvalidHandshake: If the Sec-WebSocket-Extensions header is invalid.

If several subprotocols are supported by both the client and the server, pick the first one in the list declared the server. If the server doesn't support any subprotocols, continue without a subprotocol, regardless of what the client offers. If the server supports at least one subprotocol and the client doesn't offer any, abort the handshake with an HTTP 400 error. You provide a ``select_subprotocol`` argument to :class:`ServerProtocol` to override this logic. For example, you could accept the connection even if client doesn't offer a subprotocol, rather than reject it.
