FAQ - Favorites synchronization
CORS policy
All endpoints are allowing all origins for CORS calls.
Header: Access-Control-Allow-Origin: *
Internet Explorer 8+9 compatibility
CORS management with Internet Explorer 8 and 9 is possible, using a jQuery plugin (http://api.brain-map.org/examples/doc/scatter/javascripts/jquery.ie.cors.js.html).
OPTIONS header - Known issue
The OPTIONS request is not managed for now. Using Angular-JS will not possible as they are using a OPTIONS request first.
For the time being, please use jQuery instead for Favorites sync API calls.
