Overview
Undertow is a web server written in Java. It provides both blocking and non-blocking APIs based on NIO. It has a composition-based architecture that allows assembling a web server combining small single purpose handlers.
Undertow is embeddable, its lifecycle is controlled by the embedding application and its configuration is controlled programmatically via API calls. Undertow is the default web server in WildFly, and in this case the configuration is exposed via XML in the server configuration file as:
...
<subsystem xmlns="urn:jboss:domain:undertow:3.0">
...
</subsystem>
...
.
It has support for Servlet 3.1.
