In Erlang, it's extremely easy to trace functions, so that you can check which function has been called, when, and what it's returning.
In your case, you might be interested in the function: e_dispatcher:dispatch/1 Tracing functions will help you (a lot!) in understanding how the whole Erlang Web framework works.
