How to redirect user's browser URL to a different page in Nodejs?

response.writeHead(301,
  {Location: 'http://whateverhostthiswillbe:8675/'+newRoom}
);
response.end();

For those who (unlike OP) are using the express lib:

http.get('*',function(req,res){  
    res.redirect('http://exmple.com'+req.url)
})

OP: "I would love if there were a way to do it where I didn't have to know the host address..."

response.writeHead(301, {
  Location: "http" + (request.socket.encrypted ? "s" : "") + "://" + 
    request.headers.host + newRoom
});
response.end();
