Hi guys, I've post this question at
stackoverflow<http://stackoverflow.com/questions/12833673/weird-behaviour-with-nodejs-and-apache-benchmark>,
but I thought this group might be a better place for it:
I'm testing out nodejs (0.8.11).
with the following server app:
var http = require('http');
http.createServer(function (req, res) {
console.log('hit!');
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');
I ran apache benchmark:
ab -r -v 4 'http://127.0.0.1:1337/'
I get the following output:
hit!
hit!
hit!
hit!
hit!
hit!
hit!
hit!
hit!
... (alot more)
output from ab:

and thinking the default number of requests isn't 1 as is specified in ab
manual, i tried:
ab -v 4 -n 1 -c 1 'http://127.0.0.1:1337/'
I get the same output (alot of 'hits!' in the log)
I would expect there to be only one 'hit!' message in the log when it is
hit with 1 request... The funny thing is, the application behaves correctly
(with only 1 'hit!' message in the log) when I curled it.
What is going on here?
This is specific to node, I've tried the same with my jetty app, with `ab
-c 1 -n 1`, there was only 1 recorded hit...
