	English When implementing an HTTP server that also supports WebSocket, the server usually reads the HTTP request from the client. To detect when the incoming HTTP request is a WebSocket Upgrade request, the function [link beast.ref.boost__beast__websocket__is_upgrade `is_upgrade`] may be used.

	English Once the caller determines that the HTTP request is a WebSocket Upgrade, additional overloads of [link beast.ref.boost__beast__websocket__stream.accept `accept`] and [link beast.ref.boost__beast__websocket__stream.async_accept `async_accept`] are provided which receive the entire HTTP request header as an object to perform the handshake. By reading the request manually, the program can handle normal HTTP requests as well as upgrades. The program may also enforce policies based on the HTTP fields, such as Basic Authentication. In this example, the request is first read in using the HTTP algorithms, and then passed to a newly constructed stream:

	English The WebSocket protocol understands the concept of subprotocols. If the client is requesting one of a set of subprotocols it will set the header [@https://tools.ietf.org/html/rfc6455#section-11.3.4 Sec-WebSocket-Protocol] in the initial WebSocket Upgrade HTTP request. It is up to the server to parse the header and select one of the protocols to accept. The server indicates the selected protocol by setting the [@https://tools.ietf.org/html/rfc6455#section-11.3.4 Sec-WebSocket-Protocol] header in the accept header.
