Save session in swift http request

Question

In my application, I use JSON, and I recently made a session, so if I would like to make some HTTP request to get data for a specific user, the user must log in earlier (also used by http request). in safari, when I enter the login url and then the url of the received data, it does this as necessary. but in my application, I first call the login, and then the URL to receive the data, but it probably starts a new session in each url request, which causes me to get an error and not receive the data. my url request function:

static func urlRequest (adress: String, sessionEnded: (NSDictionary->Void)?){
    println(adress)
    var urli = NSURL(string: adress)
    var request = NSURLRequest(URL: urli!)
    var rVal = "";
     self.task = NSURLSession.sharedSession().dataTaskWithURL(urli!) {(data, response, error) in
        var parseError: NSError?
        let parsedObject: AnyObject? = NSJSONSerialization.JSONObjectWithData(data,
            options: NSJSONReadingOptions.AllowFragments,
            error:&parseError)
        let po = parsedObject as NSDictionary
        if let a = sessionEnded{
            sessionEnded!(po)
        }
    }
    task!.resume()

}

Thanks in advance!

    if responseDictionary == nil {
