VERBd to it, and keeps statistics of it.
web/null is great to use as a diagnostics end-socket of any distributed system you have, that works against another system sitting at an HTTP endpoint.

npm. It is preferrable (but not must) to run globally (sudo, -g)
$ sudo npm install webnull -g $ webnull == web/null v0.0.4. I eat your HTTP. == * Listening on port 4000. * Flushing to webnull.log every 10 seconds.
Alternatively, if you'd like to clone / run and tweak, clone this repository and run
$ npm install
You should then be able to run
$ node webnull == web/null v0.0.4. I eat your HTTP. == * Listening on port 4000. * Flushing to webnull.log every 10 seconds.
And now just experiment. Here is apachebench
$ ab -n 10000 -c 10 "http://localhost:4000/"
