/// Minimal Java HTTP server class.
// <P>
// This class implements a very small embeddable HTTP server.
// It runs Servlets compatible with the API used by JavaSoft's
// <A HREF="http://java.sun.com/products/java-server/">JavaServer</A> server.
// It comes with default Servlets which provide the usual
// httpd services, returning files and directory listings.
// <P>
// This is not in any sense a competitor for JavaServer.
// JavaServer is a full-fledged HTTP server and more.
// Acme.Serve is tiny, about 1500 lines, and provides only the
// functionality necessary to deliver an Applet's .class files
// and then start up a Servlet talking to the Applet.
// They are both written in Java, they are both web servers, and
// they both implement the Servlet API; other than that they couldn't
// be more different.
// <P>
// This is actually the second HTTP server I've written.
// The other one is called
// <A HREF="http://www.acme.com/software/thttpd/">thttpd</A>,
// it's written in C, and is also pretty small although much more
// featureful than this.
// <P>
