How to simulate a slow HTTP server with a Dockerized lighttpd

Today I had to work on an issue related to troubled HTTP connections. So in order to reproduce such issue I had to find a way to easily reduce the bandwidth of the HTTP transfer.

After a quick Google search I landed on this Stackoverflow answer which suggested me the idea to create a simple Docker container for that.

The container image is automatically build on Dockerhub from the Dockerfile.

The container can be easily used to serve a local folder or as a proxy in front of another HTTP server.
