+# httpserver
+
+A simple http server designed for embedding based on the JDK sun.net.httpserver.
+
+It adds websocket support using modified source from nanohttpd.
+
+All async functionality has been removed. Most synchronized blocks were removed in favor of other Java concurrency concepts.
+
+The end result is an implementation that supports adoption of Virtual Threads available in JDK 21.
+
+## using
+
+Set the default HttpServer provider when starting the jvm:
+
+<code>-Dcom.sun.net.httpserver.HttpServerProvider=robaho.net.httpserver.DefaultHttpServerProvider</code>
+
+## future work
+
+There is no http2 support.
