• Cheat sheet:

Compile modified handles without restarting server:

c("src/elli_demo_handler.erl", [{outdir,"ebin/"}]).

Debug the handler - start debugger, load demo_handler module and add break point to handle first function:

debugger:start().
ii(elli_demo_handler).
ib(elli_demo_handler, handle, 2).

Enjoy!
