I am also having the same issue.
My objective is to create a apache/jetty hosted business website that uses Splunk javascript SDK. I want the javascript features from SDK to work without using node.js. AFAIK, the purpose of node.js is to provide a /proxy service (endpoint) for the javascript calls to Splunk server. We need a /proxy kind of service to be running on our business webserver because Cross-origin resource sharing (http://en.wikipedia.org/wiki/Cross-origin_resource_sharing) is not allowed, or in simple words, a browser on which our business website is open, cannot make a direct call to splunk server on its own.
I am also looking for a way where I can avoid using node.js server or creating a /proxy service on my apache/jetty server. I am sure that splunk would not release an SDK with the constraint of using node.js as the only server. I have posted my question on : http://answers.splunk.com/answers/189901/by-pass-proxy-service-for-javascript-sdk.html. I would appreciate if someone can put morel light on this architectural issue.
