Does not support concurrent requests

I am writing a node app that caches data from several different sharepoint collections, but problems occur when you perform simultaneous requests (I have each data endpoint caching concurrently). It seems as though the last request overrides any requests that have not yet completed. All requests will complete and call their callback function, but each callback contains the data from the last request made.

When running each request after the previous has returned, the issue does not arise, it is only when there are multiple requests made at a time.

var request = require('node-http-ntlm');
var urls = [
    'url1', //Returns 'data1'
    'ur2', //Returns 'data2'
    'url3' //Returns 'data3'
];
var opt, i;
for(i in urls){
    opt = {
        url: urls[i],
        //..credentials
    }
    request.get(opt, function(err, res){
        if(err){
            console.info(err);
        }else{
            console.info(res);
        }
    });
}

Should print (in no particular order, depending on which requests return first):

data1
data2
data3

actual output is

data3
data3
data3

Sorry @SamDecrock, any thoughts on the above?

I’m using setImmediate() in my code. This means that requests can be interrupted by other events. I suppose the server can’t handle 3 concurrent authentications from the same client.

I suppose you don’t really want to authenticate 3 times. Can’t you authenticate once and the use the received cookies to stay in the session.
