Hi,
I’m currently running my own instance of openrouteservice (thanks so much by the way it’s awesome 
)
I’m interested in the alternative route feature. It give good results when I try it on the openrouteserviceorg api , but I get a different result on my own server.
For a given start and arrival point the openrouteserviceorg api, is returning 2 possible routes, but my self hosted version return only one.
I guess it could be a configuration issue ? (app.config file)
Could someone provide the app.config file used by openrouteserviceorg ?
