Wow. I was trying to use RPC to get past SOP. I can't deploy them together because I need the development environment to develop and that means separate environments. Having two backends communicate adds an undesired additional layer.
I had JSONP working just fine but couldn't get two way communications when getting past SOP. I could only pass data in one direction. Most of my backend uses web services. Is there anyway to get to that? Thanks for the help.
