Handle websocketpp connection path

I'm really newbie in websocketpp. Can you tell me please, how can i get websocket connection path on new connection in my server? I mean i need to get the part of this:

ws://localhost:8080/addr1    ------> get addr1
ws://localhost:8080/addr2    ------> get addr2
ws://localhost:8080/etc      ------> get etc

I'm using now an example from this link: http://ift.tt/1FQuPwR
