	English ↹ ↵ NBS … “ ” ‘ ’ ﹙-﹚ ‐ – — Because a serialized header is not length-prefixed, algorithms which parse messages from a stream may read past the end of a message for efficiency. To hold this surplus data, all stream read operations use a passed-in __DynamicBuffer__ which must be persisted between calls until the end of stream is reached or the stream object is destroyed. Each read operation may consume bytes remaining in the buffer, and leave behind new bytes. In this example we declare the buffer and a message variable, then read a complete HTTP request synchronously: 546/10000 · 546

When not using a flat buffer the implementation may perform an additional memory allocations to restructure the input into a single buffer for parsing. 305/10000 · 305

	English ↹ ↵ NBS … “ ” ‘ ’ ﹙-﹚ ‐ – — 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. 562/10000 · 562

This is one technique which may be used to impose a limit on the maximum size of an HTTP message header for protection from buffer overflow attacks. The following code will print the error message: 415/10000 · 415
