and edit **source\app.d** to call your own user-created function **helloAgain()**
```d
import vibe.vibe;
void main()
{
auto settings = new HTTPServerSettings;
settings.port = 8080;
settings.bindAddresses = ["::1", "127.0.0.1"];
auto router = new URLRouter;
router.get("*", serveStaticFiles("public/"));
router.get("/", staticTemplate!"notsimplehello.dt");
router.get("/about", staticTemplate!"about.dt");
router.get("/contact", staticTemplate!"contact.dt");
router.get("/events", staticTemplate!"events.dt");
router.get("/helloagain",&helloAgain);
auto listener = listenHTTP(settings, router);
scope (exit) listener.stopListening();
runApplication();
}
void helloAgain(HTTPServerRequest req, HTTPServerResponse res)
{
res.writeBody("Hello again, World!");
}
```
Compile and run then refresh your browser to **localhost:8080/** and click on the **Hello again!** link and you will see that the new function gets called
