It is definitely running twice, why is that?

The browser is probably requesting "/favicon.ico" in addition to "/".
Try to print req.requestURL to know for sure.

yep it is requesting favicon.ico, any fix for this? as almost all codes runs twice because of this...

There is no real "fix" for this, because the browser will just do that
no matter what, but you'd usually just restrict the code to run only for
a particular URL. The typical way for low-level code is to use a
URLRouter and then call router.get("/", &hello); and pass router
to listenHTTP. See also http://vibed.org/docs#http-routing.
