var foo = function() {
    return {
        sendHttpPostToBlitline : function(job_data, callBackBitline) {
	    var http = require('http');
	    var json_job_data = new Object();
	    json_job_data.json = job_data;
	    var job_data_stringified = JSON.stringify(json_job_data);
	    var options = {
		host : 'api.blitline.com',
		port : 80,
		method : "POST",
		path : '/job',
		headers : {
		    'Content-Type' : 'application/json',
		    'Content-Length' : job_data_stringified.length
		}
	    };
	    console.log("Submitting to Blitline size(" + job_data_stringified.length + ") Job Data :" + job_data_stringified);
	    var req = http.request(options, callBackBitline);
	    req.write(job_data_stringified);
	    req.end();
	}
    }
}();
 
//Using this 
 
foo.sendHttpPostToBlitline(job_data,callBackBitline);
 
//Where job_data is the blitline request javascript object and callbackblitline is the return function
