Well got it working with the help of Sascha’s post.
Quick summary:
Put it in the dashing’s project public folder
Added the following line to the config.ru located at the root of the project folder
set :outboard_file, ‘http://localhost:3030/outboard.txt’
Restarted it and it works like a charm
I would advise against doing this on a public webserver but I think anyone trying their hands at this will know that.
Exactly what I needed!
