I have an existing jQuery plugin which makes a lot of AJAX calls (mostly JSON). I am wondering what is the quickest to allow it to do cross-site calls i.e. the $.get and $.p
You can also use CORS instead of JSONP, works with ff,chrome,safari. CORS is less troublesome to setup and requires only a filter in server-side.
Please go through this article.Well explained and similar. Only constraint is IE does not support this and older versions of FF,chrome also has some issues.
