Show HN: A dummy web server to return arbitrary responses to test your services

Hi everyone, I realize this is not terribly exciting or inventive but when testing a large company's infrastructure from the inside and outside, I noticed that there are a lot of services that I do not have easy access to that I would still like to test.

So imagine you have a reverse proxy that looks at a certain host and you'd like how that reverse proxy reacts if you send it a 200, 201, 400 or 500. Somehow I couldn't find such a tool and so I built a small dummy web server to do that.

Hopefully someone will find it helpful.
