public boolean init(Server server,
                    String prefix)
Handler
init in interface Handlerserver - The HTTP server that created this Handler.
		Typical Handlers will use Server.props
		to obtain run-time configuration information.prefix - The handlers name.
		The string this Handler may prepend to all
		of the keys that it uses to extract configuration information
		from Server.props.  This is set (by the Server
		and ChainHandler) to help avoid configuration parameter
		namespace collisions.
true if this Handler initialized
		successfully, false otherwise.  If
		false is returned, this Handler
		should not be used.
public boolean respond(Request request)
                throws IOException
Handler
respond in interface Handlerrequest - The Request object that represents the HTTP
		request.
true if the request was handled.  A request was
		handled if a response was supplied to the client, typically
		by calling Request.sendResponse() or
		Request.sendError.
IOException - if there was an I/O error while sending the response to
		the client.  Typically, in that case, the Server
		will (try to) send an error message to the client and then
		close the client's connection.
		
		The IOException should not be used to silently
		ignore problems such as being unable to access some
		server-side resource (for example getting a
		FileNotFoundException due to not being able
		to open a file).  In that case, the Handler's
		duty is to turn that IOException into a
		HTTP response indicating, in this case, that a file could
		not be found.
