CORS & API key: anyone found a fix?

Hey guys, I was reworking my AngularJS project that fetches my destiny info to contain my api key. however, adding this custom header seems to break my app. I've been forced to use a proxy service (was using http://crossorigin.me/ but tried heruko as well) so my app can run flawless, however, as soon as I include my api key header i'm running into the CORS issue again since neither services seem to forward my custom header (or when i include my custom header they seem to not include their own CORS headers). Anyone else stumble onto this issue? able to get past it? If not I guess I'll have to see if i can setup another fix for the issue. just wanted to keep with angularJS for learning purposes for myself :)
