HTTP Server configuration

• buf_len is the buffer size used for the underlying tcp socket channel. The default value is 16_000 bytes.

• max_connections is the maximum number of concurrent connections that can be active within a server. The default behavior is to have no upper bound on this number.

• max_accepts_per_batch is the maximum number of socket connections that a server will attempt to accept in a single accept call. The default value is 1.

• backlog is the number of clients that can have a pending connection. Additional connections can be rejected, enqueued or ignored based on the underlying operating system's behavior.

• write_timeout is the maximum duration that the underlying socket will wait for any pending write syscalls to finish.

• read_header_timeout is the maximum time span that the server loop is allowed to read a request's headers. The default value is 60 seconds. If read_header_timeout is zero then no timeout is used, and the server could potentially wait forever attempting to read enough data to parse request headers.

• error_handler allows customizing how unhandled exceptions, and any potential parsing or i/o errors get rendered. The default implementation will attempt to send an HTTP response with a status code and an empty body.
