1. Add a ~/.powconfig file and set the POW_EXT_DOMAINS env variable to handle the 'do' top level domain (as outlined here http://pow.cx/manual.html in section 3.1).

2. Open Activity Monitor and force quit pow to load the new env variable.

3. Add the following line to the end of your host file:
  127.0.0.1 sched.do

Now you can access local sched.do at http://sched.do and production sched.do at https://www.sched.do
