To obtain the serialized next buffer sequence, call [link beast.ref.boost__beast__http__serializer.next `serializer::next`]. Then, call [link beast.ref.boost__beast__http__serializer.consume `serializer::consume`] to indicate the number of bytes consumed. This updates the next set of buffers to be returned, if any. `serializer::next` takes an error code parameter and invokes a visitor argument with the error code and buffer of unspecified type. In C++14 this is easily expressed with a generic lambda. The function [link beast.ref.boost__beast__http__serializer.is_done `serializer::is_done`] will return `true` when all the buffers have been produced. This C++14 example prints the buffers to standard output:

* A body that does not entirely fit in memory.
* A body produced incrementally from coroutine output.
* A body represented by zero or more buffers already in memory.
* A body whose size is not known ahead of time.
* Body data generated dynamically from other threads.
* Body data computed algorithmically.

The boundaries between frames of a multi-frame message are not not considered part of the message. Intermediaries such as proxies which forward the websocket traffic are free to "reframe" (split frames and combine them) the message in arbitrary ways. These intermediaries include Beast, which can reframe messages automatically in some cases depending on the options set on the stream.

A WebSocket session begins when a client sends the HTTP/1.1 [@https://tools.ietf.org/html/rfc7230#section-6.7 Upgrade] request for [@https://tools.ietf.org/html/rfc6455#section-1.3 WebSocket] on an established connection, and the server sends an appropriate response indicating that the request was accepted and that the connection has been upgraded. The Upgrade request must include the [@https://tools.ietf.org/html/rfc7230#section-5.4 Host] field, and the [@https://tools.ietf.org/html/rfc7230#section-5.3 target] of the resource to request. A typical HTTP Upgrade request created and sent by the implementation will look like this:
