[GraphHopper] Change a node without build to times

[marcosi66 at virgilio.it]

Hello, 
I have downloaded grapphoper on my pc and I'm doing test on it, I create a server in witch there is grapphopper( for not running in localhost:8989).
I am modifying the map.osm for test,
The problem I have is this:
I want to see one time the result of calculate a route to point A to B and at the second time I want to change a node(for example to add a barrier) in my map(to do that I change a node in the map.osm) and recalculate the route but I don't want to restart the server and calculate the route(I don't want to turn off the server but that refresh the page with an alert("Waiting") for the user).
The problem is that: I want to modify automatically  often the map.osm and recalculate route but avoiding to restart everytime the server to rebuild the graph.
Thank you
