[keycloak-user] Webpage reloading twice

Hi, We are using the Javascript Adapter from Keycloak for our client authentication. However, when accessing a webpage, we receive the information twice. Here are the request logs received from the client to the server: 127.0.0.1 - - [13/Sep/2016 10:23:10] "GET /f/services HTTP/1.1" 200 - 127.0.0.1 - - [13/Sep/2016 10:23:10] "GET /f/services?prompt=none HTTP/1.1" 200 - The client is calling a second GET request for a reason that I don't know. Can you explain? Thank you
