Hi, i've started to add jsonp support to aerogear.js pipeline and i wanted to get some feedback that i'm on the right track i have a example project here : https://github.com/lholmquist/WoWAerogear those of you with yeoman installed can type "yeoman build" then "yeoman server", you might be able to get away with just the second command. There are 2 requests, the first using jQuery, so i had a baseline, and the second is with a modified version of aerogear.js pipeline.add( { ……. settings: { ………... jsonp: true, callback: "myCallback" } } ); I think declaring it during the creation makes sense. Being able to override the jsonpCallback would add a layer of security for when the server defines the callback, I not sure if this should be put into a jsonpSettings:{ } or leave it were it is i only tested read atm, just wanted to get some feedback first -Luke
