as Publisher) can produce data that an HTTP server (acting as Subscriber) can then write to the response. The 2 main purpose of Reactive Streams is to let the subscriber control how quickly or how slowly deserialization of HTTP request and response content. 1.2.1. HttpHandler HttpHandler is a simple contract with a single method to handle a request and a response. It is intentionally minimal, and its ResponseStatusExceptionHandler Provides handling for exceptions of type ResponseStatusException by setting the response to the HTTP status code of the exception. WebFluxResponseStatusException Handler Extension of

logical String-based view names returned from a handler to an actual View with which to render to the response. See View Resolution and View Technologies. LocaleResolver, LocaleContextResolver Resolve the controllers) is run to prepare a model for rendering. Alternatively, for annotated controllers, the response can be rendered (within the HandlerAdapter) instead of returning a view. • If a model is returned as any others. By default, this is set to false, in which case the DispatcherServlet sets the response status to 404 (NOT_FOUND) without raising an exception. Note that, if default servlet handling

tight relationship between requests and responses. Most messaging systems also support a request-response mode but this is not a primary feature of messaging systems. Designing systems to be asynchronous to use your network bandwidth to its full capacity. With an RPC approach you have to wait for a response for each request you make so are limited by the network round trip time, or latency of your network that sent messages have reached the server without having to block on each message sent until a response is received. Blocking on each messages sent is costly since it requires a network round trip for
