app.all(/^\/$/, function(request, response, next) {
    request.url=config.defaultRootDocument;
    if(logMode>=mumble) console.log(" Using root document default: " + config.defaultRootDocument);

}

// Add Dynamic script support
nscript.docRoot = config.docRoot;
nscript.defaultRootDocument = config.defaultRootDocument;
nscript.cgiEngine = config.cgiEngine;
app.all(/./,nscript.expressLaunch);

// Apply static page server for the rest
app.use(express.static(config.docRoot));
app.use(express.favicon(config.docRoot + '/favicon.ico')); 
console.log("Serving static files at: " + config.docRoot);
