Regarding the modifications to lib/request.js mentioned: #30 (comment)

http-headers are supposed to be case insensitive I know @mikeal of request has been adamanat about this.

Sounds like a bug with the phantomjs server.

Basically would need a simplified version of request, maybe just use native node api. Probably wouldn't be too bad given that we have pretty consistent request patterns and don't need a lot of other stuff in there. Not to high on my priority list, but if someone wrote a patch I'm all for it.
