Sometimes it is necessary to send a message whose body is not conveniently described by a single container. For example, when implementing an HTTP relay function a robust implementation needs to present body buffers individually as they become available from the downstream host. These buffers should be fixed in size, otherwise creating the unnecessary and inefficient burden of reading the complete message body before forwarding it to the upstream host.

The Subject Alternative Name (SAN) is an extension in X.509 certificates that allows multiple domain names, subdomains, or IP addresses to be associated with a single SSL/TLS certificate. Before that it was the Common Name field in the certificate subject which could contain a single hostname.

Messages may also be read asynchronously. When performing asynchronous stream read operations the stream, buffer, and message variables must remain valid until the operation has completed. Beast asynchronous initiation functions use Asio's completion handler model. This call reads a message asynchronously and reports the error code upon completion. The handler is called with the error, set to any that occurs, and the number of bytes parsed. This number may be used to measure the relative amount of work performed, or it may be ignored as this example shows.

This function returns an iterable range representing the passed buffer sequence. The values obtained when iterating the range will always be a constant buffer, unless the underlying buffer sequence is mutable, in which case the value obtained when iterating will be a mutable buffer. It is intended as a notational convenience when writing a ['range-for] statement over a buffer sequence.

The function [link beast.ref.boost__beast__buffers_range_ref `buffers_range`] maintains a copy of the buffer sequence, while [link beast.ref.boost__beast__buffers_range_ref `buffers_range_ref`] maintains a reference (in this case, the caller must ensure that the lifetime of the referenced buffer sequence extends until the range object is destroyed).
