Package io.undertow.servlet.handlers

Class DefaultServlet

java.lang.Object

jakarta.servlet.GenericServlet

jakarta.servlet.http.HttpServlet

io.undertow.servlet.handlers.DefaultServlet

All Implemented Interfaces:

jakarta.servlet.Servlet, jakarta.servlet.ServletConfig, java.io.Serializable

public class DefaultServlet
extends jakarta.servlet.http.HttpServlet

Default servlet responsible for serving up resources. This is both a handler and a servlet. If no filters match the current path then the resources will be served up asynchronously using the HttpHandler.handleRequest(io.undertow.server.HttpServerExchange) method, otherwise the request is handled as a normal servlet request.

By default we only allow a restricted set of extensions.

todo: this thing needs a lot more work. In particular: - caching for blocking requests - correct mime type - range/last-modified and other headers to be handled properly - head requests - and probably heaps of other things
