Hi, I am thinking about dropping JSONP support in Searchisko going forward. We do support CORS to certain extent. My experience with JSONP (from the POW of JS/HTML developer) has been mixed or even worse. On the other hand I think there is quite solid support of CORS these days http://caniuse.com/cors I think we can expect that web browser clients will be used mostly for search (i.e. GET) operations and not for data PUT/POST anyway. Here is relevant issue https://github.com/searchisko/searchisko/issues/15 Regards, Lukas Vlcek jboss.org Development Team
