From 6aa6fd2140e3124798f45d5f732b8a776ee5b87f Mon Sep 17 00:00:00 2001 From: Dan Cartoon Date: Sun, 8 Apr 2012 18:37:07 -0700 Subject: [PATCH] Adding JSONP support for Cross-Domain support during refreshes Changing the refresh call to use jQuery, which has built-in support for JSONP, which enables cross-domain requests. Graphite already supports this style of request, so it's a little simpler to do this than some of the alternatives for cross-domain support --- app/js/graphene.coffee | 13 +++++++++++-- build/index.js
