JEP 408 (Java 18): Simple Web Server with new enhanced request handling

“The core functionality of the Simple Web Server is provided by its handler. To support extending this handler for use with existing code, we introduce a new HttpHandlers class with two static methods for handler creation and customization as well as a new method in the Filter class for adapting a request.

handleOrElse complements a conditional handler with another handler, while the factory method of lets you create handlers with pre-set response state. The pre-processing filter obtained from adaptRequest can be used to inspect and adapt certain properties of a request before handling it. Use cases for these methods include delegating exchanges based on the request method, creating a “canned response” handler that always returns a certain response, or adding a header to all incoming requests.”
